CM907

PROGRAMMABLE THERMOSTAT

PRODUCT SPECIFICATION SHEET

The CM907 thermostat is designed to provide automatic time

and temperature control of heating or cooling systems in

villas and apartments.

It can be used as part of a system in conjunction with combi-

boilers, oil-burners and gas fired boilers, circulation pumps,

thermal actuators, zone valves and electric heat systems

(<8A).

The CM907 is designed with the installer in mind and

includes a moulded back-plate with trunking guides and

wiring breakouts to make installation quick and easy.

The CM907 extra large LCD display, dynamic text display,

button layout based on the same simple programming

philosophy used on our acclaimed CM60 products and the

introduction of an ‘OK’ button, makes it easier to install and

more user friendly.

The unit is ideal for consumers who want reliable precise

temperature control from a modern looking, simple to

ram and eas

to use

roduct.

FEATURES

• Attractive, slim, ultra-modern styling makes it ideal for

location in any type of home.

• 7-day heating program.

• A dynamic text display on the LCD that gives enhanced

feedback to the user / installer.

• Up to 6 daily independent time and temperature level

changes let you set 6 time and temperatures pairs to suit

your lifestyle.

• LCD Backlighting to illuminate the display for easier viewing

in low light conditions.

• Temporary programmed temperature override to override

the programmed temperature till the next switch point.

• Party feature that temporarily maintains a selectable

constant temperature for 1-23 hours, then returns to normal

operation.

• Day Off feature that follows Sunday’s program for 1 to

99 days, allowing selection of a different heating program

without having to re-program the thermostat.

• Holiday button that provides energy savings by reducing

to a constant temperature from 1 to 99 days when people are

on holiday, returning to normal operation (AUTO or

MANUAL) on the day of their return.

• Room Temperature Enquiry.

• EEPROM memory holds the user program indefinitely.

• OFF position has an integral frost protection setting at

minimum 5°

°°C (installer adjustable) so that pipes in the

house will never freeze in winter.

• 24...230V 8A resistive, 3A inductive SPDT relay provides

compatibility with most domestic central heating systems

reducing the need to stock many different models.

• Battery powered by 2 x AA size (LR6) alkaline cells.

• Minimum battery life of 2 years with low battery warning

cato

• Built-in default heating program.

• Automatic Summer / Winter time change adjusts the time

automatically to daylight saving time.

• Telephone interface can be fitted to allow remote switching

between program modes and a fixed set-point.

• Surface or wall-box mounting options with trunking guides

and wiring breakouts to simplify installation.

• No installer links or special installer switches on the back of

the unit mean no adjustment is required for combi-boilers

and most domestic central heating systems.

• User Set-Up Mode allows extra functions to be set at the

discretion of the user:

• AM-PM or 24hr time display.

• Resetting the heating profile to factory default.

• Enable / disable of Auto Summer / Winter time change.

• Languages selection of the user interface (on selected

models only).

• Installer Set-Up Mode allows extra functions to be set at the

discretion of the installer to match the consumers

applications and needs:

• Optimisation.

• Pump Exercise.

• Upper / Lower Set point Limit Adjust.

• Temperature offset.

• Minimum ON time.

• Cycle rate.

• Heat / Cool operation.

• Proportional Band Width.

• Diagnostic Mode to assist in faultfinding.
