II−icomfort Touch

 thermostat (if applicable)

In communicating applications the Lennox icomfort
Touch

 thermostat must be used. In these applications the

icomfort Touch

 thermostat overrides the DIP switch set-

tings on the integrated control. Refer to the illustrations pro-
vided with the thermostat for installation, set−up and opera-
tion.

See figures 16 and 17 for icomfort Touch

 thermostat wir-

ing in communicating applications.
