Setting-up the Thermostat
Please follow the illustrations detailed on page 1 in sequence to install the thermostat correctly, then refer to the steps below:
NOTE: Using the For gas boiler applications, the factory system settings will not need to be changed (for other applications see section ‘
Thermostat for Specic Applications’ below).
To set-up the thermostat:
1. Remove the battery cover and insert the batteries supplied with the unit (2 x AA LR6 Alkaline Batteries).
2. DATE Move the slider switch to the position.
3. Use the or buttons to set the correct day / month / year, pressing the green button to conrm.
4. Use the or buttons to set the correct time, pressing the green button to conrm.
5. Move the slider switch to the required operating mode (AUTO MAN OFF, or ) to begin operating at the default factory settings, or move to
PROG and modify the built-in heating program accordingly (see User Guide).
You can now use the ‘User Guide’ supplied with the thermostat to demonstrate how it works to the home owner.
Using the Thermostat for Specic Applications
The CM900 thermostat is a versatile controller that can be used to control many different applications. For most typical applications, like ‘wall-hung
gas red combination boiler control’ or ‘zone valve control’, no adjustments from the factory settings are required.
For other applications, like controlling an oil burner, the best system performance can be achieved by modifying selected parameters of the
thermostat in installer’s mode. The table below lists the most common settings used for a specic application:
Removing the Cover
Specic Application:
HEATING
AIR-CONDITIONING
Setting: What to change:
Gas Boiler (<30kW)
Oil Boiler
Thermal Actuator
Zone Valve
Electric Heating
(resistive load <8A)
Heat Pump / Air-
Conditioner
Fan Coil
Note: All parameters listed below belong to category 2
- System Parameters (see Installer Parameters Table)
No changes required
Set 1:Ot parameter to 4
Set 2:Cr parameter to 3
Set 2:Cr parameter to 12
No changes required
Set 2:Cr parameter to 12
Set 3:EH parameter to 1
To enable switching between cooling and heating modes
adjust parameter 4:HC in category 2 (0 = disabled, 1 =
enabled). Now you can switch between these modes by
pressing the and buttons together for 5 seconds in
any of the product operating modes (AUTO MAN OFF, or ).
Explain to the end user how to switch between these modes
using the and buttons and ensure the cooling program
is modied as required.
Set 1:Ot parameter to 4
Set 2:Cr parameter to 3

Set parameter 12:tO (category 1) to
the required offset value.
Set parameter 6:uL (category 1) to the
desired upper limit.
Set parameter 7:LL (category 1) to the
desired lower limit.
The thermostat will adjust the start time in the morning/afternoon so the
desired temperature is reached by the start of the program period. The
system will restrict the start time to a max of 2 hours.
This product can be used for heating or cooling applications. If you select
cooling mode the control algorithm and factory default program will be
modied. You can independently modify the heating and cooling prole.
This feature moves time automatically on the last Sunday of March and the
last Sunday of October. The feature is factory enabled.
If the thermostat is located in a particularly hot/cold location and cannot
be moved because of wiring restrictions then the measured/displayed
temperature can be adjusted by +/- 3°C. This is useful if the homeowner
wants the reading to match another appliance temperature display.
The normal upper temperature limit of 35°C can be reduced to 21°C to save
the homeowner energy. The normal lower limit of 5°C can be increased up
to 21°C to protect inhabitants from cold.

An Outside Temperature Sensor can be tted to the thermostat, allowing the
homeowner to display the outside temperature on the display by pressing
the button.
A Remote Temperature Sensor can be tted to the thermostat, allowing it
to control the temperature from another room e.g. in commercial premises
where the public may adjust keys.
