Installation Guide
Before Installation
If you do not have the knowledge to install the thermostat safely then you
must arrange for a competent electrician to install it for you. Wiring must
conform to the current IEE regulations.
Prior to commencing the installation you must ensure the mains supply is
switched off.
- Installing the Digistat Receiver
1a. Location of the receiver
Location
The Digistat Receiver should be mounted in a convenient position, close to the boiler or central heating system wiring centre. It is recommended that the receiver is mounted on the wall nearest the final location and not less than 1m from the boiler side panel.
Warning: Installing the receiver too close to metal objects or mains cables may interfere with the radio signal.

INSTALLER OPTIONS
To make changes to the default Installer Options shown below, enter the Installer Options menu by pressing the settings button for 3 seconds. This allows access to the User Menu 01, the Advanced User Settings Menu 02, the Installer Settings 03, and Service Interval Settings 04. Use the + and – buttons to scroll to Installer Options and press O to select. You can exit the menu by pressing until you have returned to the home screen. In the Installer Options menu (Fig 7), scroll through the options using the + and – buttons and press O to select. Scroll through the different settings using the + and – buttons and press O to select and save. (Fig 8 shows Option 02 OFF).
(Option 01) Partial Sight Assistant (beep)
When enabled, audible tones indicate when the setpoint is more than, less than
or equal to the current room temperature when a user manually adjusts the
setpoint using the + button:
Setpoint > room temperature – single high tone per 0.5°C increase
Setpoint = room temperature – double tone
Setpoint < room temperature – single low tone per 0.5°C decrease
(Option 02) Frost Protection
The Digistat will switch on the heating if the temperature falls to 5°C and
maintains a temperature of 7°C even when in OFF mode.
(Option 03) Minimum Setpoint Limit
Change minimum setpoint temperature. After any changes to setpoint limits, all
setpoints in AUTO, MANUAL, BOOST and
HOLIDAY modes will be modified to conform accordingly.
(Option 04) Maximum Setpoint Limit
Change maximum setpoint temperature. After any changes to setpoint limits, all
setpoints in AUTO, MANUAL, BOOST and
HOLIDAY modes will be modified to conform accordingly.
(Option 05) Optimum Start
When enabled, this uses current ambient temperature, the next scheduled
setpoint and heat gain data captured by the device to adjust the thermostat
setpoint early, so the ambient temperature is at the required level when the
next event starts.
Delayed Start
When enabled, this uses current ambient temperature, current event setpoint
and heating characteristics of the environment to delay implementation of the
setpoint if the ambient temperature is already close to it, therefore saving
energy.
(Option 06) Valve Protection Time
In some hydronic heating systems it may be required to protect the valve by
operating it for a given time. When enabled, this maintenance feature ensures
that each relay output is operated for at least one (1) minute each week.
(Option 07) Sensor Fault Function
In the event of a sensor fault, central heating output is reduced to 30% by
turning heating ON for 3 minutes, then
OFF for 7 minutes.

User Guide
The Drayton Digistat thermostat is a universal thermostat with 24 hour, 5-2day
or 7day program types and up to 8 time/temperature events per day and can also
be used as a simple room thermostat.
Clock Setting
- Press and hold the cog button until User 01 appears,
- Press the plus button to Advanced 02, then press O to enter,

- Using the + and – you can adjust the time, then press O to save,

General Operation
Programmable thermostats do not have “On” and “Off” times like traditional
timers. They offer temperature control both day and night and you simply
select which temperatures you require at each point in the day.
With the unit in “Auto Mode” (the calendar icon is visible at the bottom of
the screen) the temperature can be changed for a short time by using the + and
– buttons. Changing the temperature in this way will keep the Digistat set to
your new temperature until the next pre-programmed event (at which time it
will revert to programmed temperature). The temperature you are setting will
flash on the screen. Once temperature is set, the unit will revert to showing
the room temperature again. The indicator will show on the screen if the unit
is calling for heat.
Programming the Digistat
Your Digistat comes with the following settings pre-programmed for your
convenience and is suitable for those working out of the house during a
typical 9-5 pattern.
