APPLICATION
The CM901 is a 1 day Programmable Room Thermostat. It is
designed to provide automatic time and temperature control of
domestic heating or cooling systems in domestic or light
commercial premises.
The slim, ultra modern design complements the extra large
LCD screen with the Line of Text (LoT)™ display and one
function button to ensure simplified programming and operation
for all users.
The CM901 can be used to control the heating circuit in a
Sundial S or Y Plan and is particularly well suited to control
combination boiler installations or additional zones in a S Plan
Plus system.
The CM901 has been designed for applications where the
householder has different heating needs for the same times
each day.
Two wire, volt free connections are ideal for use with
combination boilers.
