Honeywell CM701-UK PRODUCT SPECIFICATION SHEET

CM701 (UK Version)

PROGRAMMABLE THERMOSTAT

PRODUCT SPECIFICATION SHEET

The CM701 thermostat is designed to provide automatic time
and temperature control of heating systems in villas and
apartments.

It can be used as part of a system in conjunction with combi­boilers, oil-burners and gas fired boilers, circulation pumps,
thermal actuators, zone valves and electric heat systems
(<5A).

The CM701 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 CM701 large LCD display, button layout based on the
same simple programming philosophy used on our acclaimed
CM20 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
program and easy to use product.

FEATURES

Attractive slim, modern styling makes it ideal for
