Configuring the T7350 Thermostat
Controller (T7350)
The T7350 is a full-featured Commercial programmable
thermostat. The primary opportunity for a Commercial
thermostat is in buildings with less than 55,000 square feet.
These buildings include restaurants, shopping malls, office
buildings and banks. Commercial thermostats are used on
single zone rooftop units, split systems, heat pumps or hot/
chilled systems.
The electronic thermostat consists of two pieces, the cover
assembly and a subbase. The subbase(s) include the
equipment control connections. The subbase is mounted on
the wall and the thermostat cover assembly is mounted on the
sub base. Different subbases will be used for different
applications including; up to Three Heat/Three Cool or Two
Heat/Four Cool, modulating outputs, and dehumidification
high limit control. Each subbase is compatible with the
common cover assembly.
