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.

1. Remove the front cover by releasing the 2 screws at the
bottom. Mounting holes and electrical connections
are found underneath the hinged black cover (Fig 1).

2. Fix back plate directly onto the wall using suitable wall plugs
and screws or mount over existing wall box (Fig 2).

3. Complete the wiring according to the connection suggestions
shown in (Fig 3). For Basic boiler, Combi boiler and Basic boiler
with zone valve applications Digistat with battery or mains
supply are suitable.
For Electric Heat application use Digistat with mains
supply only.

4. Close the black hinged terminal cover and replace the front
cover by locating the two latches at the top then fasten the 2
screws at the bottom (Fig 4).

5. Remove the battery cover by sliding the battery cover at the
bottom downwards (Fig 5).
6. Install the 2 AA batteries provided (Fig 6).

7. Replace the battery cover (Fig 7).

8. The Digistat is now installed and will automatically start to
control the room temperature.

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 8), 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 9 shows Option 02 OFF).

(Option 01) Partial Sight Assistant
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.

(Option 08) Application Type
Select the central heating system energy type.

(Option 09) System Capability
Select the flow capability of the heating system.

(Option 13) Installer Settings Lock
When enabled, installers can lock the installer settings menu
until a 3 digit code is entered. If the code is forgotten while
device is locked, please call the Technical Helpline.
(Option 20) Reset (Service Interval settings are NOT reset)
Reset the Digistat to its original factory settings.
Service Interval Options continued on reverse.

(Si Option 01) Si Status
Enable or disable Service Interval Mode.

(Si Option 02) Si Type
Select effect imposed on the heating when service is due.

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

Your Digistat is fitted with a “real-time clock”, which is pre-set at
the factory; you will not have to alter the time settings. A special
feature of this real-time clock is it will automatically change over
during the GMT/BST summer/winter change-over, removing the
need to manually alter the clock at these times.

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.
When the 5-2day program type is selected the pre-set
temperatures will be different Mon-Fri and Sat-Sun, as per
the tables below:

Pre-set Program 1 (24h, 5-2day weekdays, or 7day):

Pre-set Program 1 (5-2day weekend):

*To add these additional time periods manually (max. 8 per day)
please refer to the steps to the right.

What is a programmable

room thermostat?

…an explanation for householders
A programmable room thermostat is both a programmer and a
room thermostat. A programmer allows you to set ‘On’ and
‘Off ’ time periods to suit your own lifestyle. A room thermostat
works by sensing the air temperature, switching on the heating
when the air temperature falls below the thermostat setting, and
switching it off once this set temperature has been reached.
So, a programmable room thermostat lets you choose what
times you want the heating to be on, and what temperature it
should reach while it is on. It will allow you to select different
temperatures in your home at different times of the day (and
days of the week) to meet your particular needs.
Turning a programmable room thermostat to a higher setting
will not make the room heat up any faster. How quickly the
room heats up depends on the design of the heating system, for
example, the size of boiler and radiators.
Neither does the setting affect how quickly the room cools
down. Turning a programmable room thermostat to a lower
setting will result in the room being controlled at a lower
temperature, and saves energy.
The way to set and use your programmable room thermostat is
to find the lowest temperature settings that you are comfortable

with at the different times you have chosen, and then leave
it alone to do its job. The best way to do this is to set low
temperatures first, say 18C, and then turn them up by one degree
each day until you are comfortable with the temperatures. You
won’t have to adjust the thermostat further. Any adjustments
above these settings will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will usually
be only one programmable room thermostat to control the
whole house. But you can have different temperatures in
individual rooms by installing thermostatic radiator valves (TRVs)
on individual radiators. If you don’t have TRVs, you should choose
a temperature that is reasonable for the whole house. If you do
have TRVs, you can choose a slightly higher setting
to make sure that even the coldest room is comfortable, then
prevent any overheating in other rooms by adjusting the TRVs.
The time on the programmer must be correct. Some types have
to be adjusted in spring and autumn at the changes between
Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating programme,
for example, ‘Override’, ‘Advance’ or ‘Boost’. These are
explained in the manufacturer’s instructions.
Programmable room thermostats need a free flow of air to sense
the temperature, so they must not be covered by curtains or
blocked by furniture. Nearby electric fires, televisions, wall or
table lamps may prevent the thermostat from working properly.

pressing O. The new schedule will be
saved pressing O when the word
SAvE is flashing.

5. In Pre-set Program 1 you will have 4
time periods available, to add more
(max. 8 per day) press + when you see
the SAVE option on-screen and time
period 5 at the bottom of the screen,
to scroll to the Add option. Press O to
add time period then adjust time and
temperature as required.
6. To exit press to go back until you
