Customer Supplied Thermostat
The customer supplied room thermostat must be compatible
with the spark ignition control on the unit. Generally, all
thermostats that are not of the “current robbing” type are
compatible with the integrated furnace control. The low voltage
wiring should be sized as shown in Table 6.
Install the room thermostat in accordance with the instruction
sheet packed in the box with the thermostat.
Figure 17 on page 17 for an example of a typical customer
supplied wiring diagram.

Optional Factory Supplied Thermostat
The optional factory supplied T-170 commercial setback digital
thermostat (Figure 16) uses microcomputer technology to
provide precise time and temperature control. This thermostat
oers the exibility to design heating and cooling programs that
t building needs (refer to Table 7). Figure 18 for an optional
factory supplied thermostat wiring diagram.
