Can I use my CM921 to control my air-conditioning system?
Yes, if your system has been set up correctly you can use your thermostat to control
the cooling. To switch the thermostat between heating and cooling modes press
the
or
buttons together for 5 seconds in any of the product operating modes
(AUTO, MAN or OFF). The text ‘COOLING’ will be displayed for a moment on the
screen to indicate the cooling operation is now active. The factory default program
for cooling is speciied in the table below, but this can be modiied in the same way

If something happens to my heating system how can I check that the thermostat
is working?
Refer to the Troubleshooting Guide on page 15. If you still need assistance after this
call your installer. The thermostat should only be opened or removed by a qualiied
professional to prevent possible injury from electric shock and/or damage to the
