TIME O STAT 2 Channel 3 Wired HMO Thermostat
Product Information
The Time:o:stat is a versatile room thermostat that can be used to replace an existing room thermostat. It is designed for controlling heating systems in residential houses, with the exception of houses with multiple boilers or separate switched heating zones. The Time:o:stat is available in four different models: Wired (Battery), Wired (Mains), Wireless, and 2 channel.
The Time:o:stat comes with the following features:
- Countdown Heating duration
- Auto-Program modes
- Maximum Temperatures
- Minimum Temperatures
- Comfort Warmth Mode
- Night Comfort Mode Restriction
- Seasonal Mode
- Hot Water Modes (2 Channel only)
Product Usage Instructions
Countdown Heating duration
The Time:o:stat’s main operating mode involves setting a desired
temperature and time duration for the heating period. The default maximum
duration is 2 hours, but this can be changed to 3 hours using the advanced
settings. To re-start or prolong the heating period, time can be added to the
Time:o:stat at any point within the set duration limit.
Maximum Temperatures
The Time:o:stat allows you to select a maximum temperature for heating. The
default maximum temperature is 28 degrees, but it can be restricted to 23
degrees.
Minimum Temperatures
You can select a minimum temperature to ensure that the house does not fall
below a set temperature. The available options are 7, 14, 18, 19, or 20
degrees. The default setting is 14 degrees, but you can also deactivate the
minimum temperature feature.
Comfort Mode
The Comfort mode allows you to add up to 8 hours to the countdown duration
at any time of the day. The longer the period of time added to the timer, the
lower the maximum temperature limit.
Here are the temperature limits based on the duration added:
- 0-2 hours: No temperature limit (28 degrees or 23 degrees)
- 3-4 hours: Temperature limited to a maximum of 21 degrees
- 5-6 hours: Temperature limited to 20 degrees
- 7-8 hours: Temperature limited to 19 degrees
Night Comfort Mode Restriction
The Night mode restricts the Comfort mode to the night hours between 8 pm
and 8 am. This allows for longer periods of time to be added to the
Time:o:stat on cold nights but prevents the Comfort mode function from being
used during the day.
Seasonal Mode
When in Seasonal mode, the Time:o:stat will automatically change many of
its settings during the summer months. In June, July, and August, the
functions will be scaled back accordingly.
Hot Water Modes (2 Channel only)
The 2 channel Time:o:stat offers two water heating modes. You can choose
between 2 x 3-hour daily hot water heating durations or a 24-hour hot water
setting. Pressing the hot water button advances the hot water heating in the
first setting but switches the hot water off/on in the 24-hour setting.
Introduction & Features
Time:o:stat is a thermostat designed for HMO and ‘bills included’ rental properties. The Time:o:stat is tamper-proof and easy to use. It regulates temperature while controlling the heating period through a time delay countdown timer. When the time runs out the heating shuts down. This lowers heating bills while still allowing tenants to operate the heating when home – helping reduce wasted energy. Time:o:stat is a room thermostat and can be used to replace an existing room thermostat. Typically a single Time:o:stat is required per house. (Unless the house has multiple boilers or separate switched heating zones). Time:o:stat is available in four different models: Wired (Battery), Wired (Mains), Wireless and 2 channel.
Time:o:stat Features

Featured settings can be changed by following the guide for advanced settings setup in section 3.
Countdown Heating duration (Default 2 hours)
The Time:o:stats main operating mode involves setting a desired temperature
and time duration for the heating period. The default maximum duration a user
can set for each heating period is 2 hours. When this time has elapsed the
heating will stop. Time can be added to the Time:o:stat at any point to re-
start or prolong the heating period to the set duration limit. The default
duration limit is 2 hours but this can be changed to 3 hours using the
advanced settings.
Auto-Program modes (default 2 x 1 hours)
The auto-program allows a limited period of time to be automatically added to
the Time:o:stat countdown timer twice per day. This allows occupants to wake
and return to a warm house. Pressing the (:t:) button will activate auto-
program mode and bring up two start times at the top of the screen. These
start times can be easily adjusted by the occupants, but the duration is set
at installation. The default is 1 hour auto-program twice per day. This can be
adjusted in the advanced settings to 2 or 3 hours twice per day. The auto-
program default temperature is 21oC, but can be changed to 23oC. Occupants can
adjust the time the auto-programs start by holding down the (:t:) button. CH
TIMER SET is displayed, and the first auto-program start hour can be adjusted
with the (+) and (–) buttons to the right of the screen. Pressing the (:t:)
button advances to set the minutes. Pressing the (:t:) button will then
advance to set the second auto program start time. The auto-program is active
while the two times (T1 & T2) are visible at the top of the screen. Pressing
the (:t:) button will toggle the auto-program on/off. Auto-program can also be
permanently disabled in the advanced settings.
Maximum Temperatures (default 28oC)
The maximum temperature that can be selected on the Time:o:stat is 28 degrees.
This can be restricted to 23oC.
Minimum Temperatures (default 14oC)
Minimum temperatures can be selected to ensure the house does not fall below a
set temperature. These can be 7, 14, 18, 19 or 20oC. The default setting is
14oC. The minimum temperature can also be deactivated.
Comfort Mode (default deactivated)
Comfort mode can be activated in the advanced settings. This allows up to 8
hours to be added to the countdown duration at any time of the day. The
longer the period of time added to the timer the lower the maximum temperature
limit.
0-2 hours there is no temperature limit (28oC or 23oC)
3-4 hours the temperature is limited to a maximum of 21oC.
5-6 hours the temperature is limited to 20oC.
7-8 hours the temperature is limited to 19oC.
1.6 Night Comfort Mode Restriction (default deactivated) Night mode can be
activated in the advanced settings. This restricts comfort mode, detailed
above, to night hours of 8pm and 8 am. This allows longer periods of time to
be added to the Time:o:stat on cold nights but prevents the comfort mode
function being used during the day.
Seasonal mode (default deactivated)
When in seasonal mode, the Time:o:stat will automatically change many of its
settings during the summer months. During June, July and August the functions
will be scaled back to the following:
- Countdown heating duration – 2 hrs
- Auto-Program – 2 x 1hr with 48hr Auto-Drop*
- Maximum Temperature – 23oC
- Minimum Temperate – disabled
- Comfort Modes – disabled
48hr Auto-Drop deactivates the auto-program if the Time:o:stat has been left idle for 48 hours. This prevents prolonged periods of automatic heating when occupants may be away from the property. The auto-program can be reactivated by the occupants by pressing the (:t:) button.
Hot Water Modes (2 channel Time:o:stat only)
There are two water heating modes. 2 x 3hr daily hot water heating durations
or a 24hr hot water setting. Pressing the hot water button advances the hot
water heating in the first setting but switches the hot water off/on in 24hr
setting.
Quick Start Guide
- To start the heating add time to the countdown using button (A)
- Select desired temperature using buttons (C) (D)
- Additional time is added by repeatedly pressing button (A)
- The hot water can be boosted (on/off) pressing button (B)
- The auto program times can be activated by pressing button (T)
To set autoprogram times, hold button (T) for 3 seconds.
The screen will also show the current room temperature. If the target temperature is above the room temperature the radiator symbol will show and the boiler will turn on. The Time:o:stat will instruct the boiler to heat the house to the target temperature for the duration of the countdown timer. When the countdown timer runs out the Time:o:stat will stop instructing the boiler to heat the house. Additional time can be added to the countdown at any time. The tap symbol displays when the hot water tank is being heated. This can be advanced (or turned on/off) by pressing button (B).
Configuring your Time:o:stat
The Time:o:stat is shipped with the default advanced settings and locking bitswitch disabled. It is recommended that the locking bitswitch is enabled following changes to the advanced settings. This helps prevent tenants tampering with the advanced settings.

The advanced settings can be LOCKED to prevent tampering by switching bitswitch 1 to the up ‘on’ position. To do this first remove the front lower cover secured with the hex screw. Bitswitch 1 is located to the right of the T button. This will prevent changing the advanced settings until bitswitch 1 is returned to the down ‘off’ position. (Ensure mains power to the Timeostat is isolated whenever changing the any bitswitches with the wired mains model)
Setting the Time & Date
The Time:o:stat automatically adjusts for BST so it is essential to set the
correct date/time for the auto-program feature to operate correctly.
You can set the clock when new batteries are inserted, or by following the procedure below:
- Hold the left side radiator and tap buttons for 3 seconds. The date setting screen will show displaying DAY MONTH YEAR with the DAY flashing.
- Set the day using the (+) and (–) buttons.
- Press the (:t:) button will progress to set the MONTH.
- Repeat the same process to continue to set the YEAR and finally the TIME using the 24 hour clock format.
When complete the Time:o:stat screen will be blank, with the time at the top.
Changing the Wireless (RF) Channel
Normally the radio frequency (RF) channel used for the communications between
the Time:o:stat controller and receiver does not need to be changed. However
you may be operating two Time:o:stats in close proximity. This could be due to
Time:o:stats in adjacent properties or multiple boilers/zones within a
property.
To change the channel:
- Turn off the power to the boiler.
- Remove the both the Time:o:stat controller and receiver from the wall brackets.
- Adjust bitswitch settings 1.2.3.4 viewed through the aperture on the back of the receiver with a pin.
- Change the settings in the same aperture on the Time:o:stat master to match. (leave switch 5).
- Following any setting change you will need to RESET the control unit by holding the RIGHT side (+) and (-) buttons for 3 seconds. The info screen and signal strength meter will then display, press the (:t:) button to finish.
Wireless Signal Strength Test
- Perform a RESET by holding the RIGHT side (+) and (-) buttons simultaneously for 3 seconds.
- This will show the advanced settings info screen and RF signal strength meter. It shows the current signal strength in bars at the bottom of the display.
- The signal strength indicator is dynamic, so you can move the unit around to find a location with stronger signal strength.
- To exit this mode and return to normal operation press the (:t:) button.
A desirable signal strength is at least 2 bars. Below this indicates a poor signal strength. When connected there will be a small network icon displayed in the bottom right of the screen and the signal strength bars will disappear.
Wireless Time:o:stat Location Guide
Connection problems can be prevented by carefully considering the location of
the Time:o:stat master and receiver at the point of installation. The radio
frequency (RF) used by the wireless Time:o:stat passes easily through internal
stud walls but poorly through solid brick. RF is also disturbed by metal
household appliances (such as microwaves, cookers and fridges). When wiring
the receiver, mount it outside of any cupboard and where the line of signal
does not travel through the boiler itself. (Position A1 is better than B1 in
the diagram below). Typically the wireless Time:o:stat has a range of 15
meters, through three stud walls. It will only reliably pass through a single
solid brick wall and the range will be dramatically reduced. The diagram on
the following page, shows good and bad locations.
A1 to A2 location – GOOD line of signal only passing through: one wall
B1 to B2 location – BAD line of signal passing through: two walls, cupboard,
boiler, microwave and mirror.
You can check the RF signal quality of the Time:o:stat when mounted in the
desired location by following the signal testing procedure.
TROUBLESHOOTING
Q. How do I change the time?
If the incorrect time is showing then this can be changed by pressing/holding
the left hand side radiator and tap buttons for 3 seconds.
You will be asked to set the DATE, MONTH, YEAR and TIME. Use the + and –
buttons to initially change the date. Press the central (:t:) button to
confirm at each step.
Q. Low Signal displayed + flashing red LED?
- Check the orientation of the receiver and how it is mounted on the wall. The internal aerial in the black Time:o:stat receiver works best then mounted vertically in the suggested landscape orientation. Placing horizontal or in a portrait position will drastically reduce the communication range.
- Check the green light is showing on the Time:o:stat receiver next to the boiler. If the green light is not showing then there is no power. Have a qualified electrician check the wiring to the boiler.
- Check for low battery symbol showing on the Time:o:stat. If present replace the existing batteries with new high performance AA batteries.
- Check signal strength – follow the wireless signal strength testing procedure and Wireless Time:o:stat location guide.
- Check the communication channel, Time:o:stats are factory paired and do not require pairing. Changing the RF channel is only required if there are more than one Time:o:stat in close proximity. However the settings may have been inadvertently changed. You can check that the Master and receiver IDs are the same – look through the aperture on the back of both the receiver and the master and ensure the 5 bitswitch settings are the same. If changing the RF channel you must always RESET the unit by holding the right side (+) and (-) buttons simultaneously for 3 seconds.
- Check the range – The controller and its receiver may be too far apart or there are solid walls in-between the units. Relocate the wireless Time:o:stat closer to the receiver minimising metallic and solid objects in its line of sight. (follow the Wireless Time:o:stat location guide)
Q. There is a blank screen?
- DO NOT BEND THE BATTERY TERMINALS
- Try to wake the Time:o:stat by pressing the top left tap button
- Factory reset the unit by removing the batteries, then press a few buttons to clear any charge from the memory, wait for 30 seconds, then replace the batteries.
- Repeat the above procedure with new AA high performance batteries. Then RESET the unit by pressing/holding the right hand side + and -temperature buttons for 3 seconds as the settings have been changed.
Q. Low battery symbol is showing?
- Remove the batteries, then press a few buttons to clear any charge from the memory, wait for 30 seconds. Then replace the batteries with new AA high performance batteries.
- Low battery levels may be insufficient for radio frequency signal to operate correctly
Q. Heating is on when it should be off?
- RESET the unit by holding the right hand side red + and blue – temperature buttons for 3 seconds. This may have not been done following an advanced settings change.
- Check hot water usage is not being called for that would result in the boiler running.
- Check RF interference from another Time:o:stat. – If there is another Time:o:stat in close proximity then each Time:o:stat should be set to a different RF channel and then reset following the change. (A step by step guide to change the RF channel is in section 5.)
- Time:o:stats are factory paired and do not require pairing. Changing the RF channel is only required if there are more than one Time:o:stat in close proximity.
- Is the wiring correct? – this should be checked by a qualified person
- Check mains voltage has not passed through the low voltage contacts which may have damaged the unit during installation. (Maximum switchable current is 2A).
Q. Heating is off when it should be on?
- Check the boilers master thermostat is not too low. If too low then the boiler will shut off the heating regardless of the temperature selected on the Time:o:stat.
- Check the heating is set to ‘constantly on’ on the boiler. If the heating is selected as off or on a separate timer then the Time:o:stat will not operate during the other timers ‘off’ periods.
- Is the wiring incorrect? – this should be checked by a qualified person – Check mains voltage has not passed through the low voltage contacts which may have damaged the unit during installation. (Maximum switchable current is 2A).
Q. Auto-program comes on at strange times?
The two auto-program times displayed at the top of the screen run according to
the main clock in the top centre of the screen.
- Ensure this is showing the correct 24hr time.
- If the incorrect time is showing then this can be changed by pressing/holding the left hand side radiator and tap buttons for 3 seconds
