HEATING
NOTE: If a plenum fan control is used in the heating
system, there will be a short delay on a call for heat to
allow the furnace to heat the plenum. The fan starts
immediately in electric heat systems. Allow 30 seconds
for the damper to open or close completely.
Make sure all zone thermostats are set as instructed in
the Heating column in Table 5. Check each zone thermo-
stat as follows:
1. If thermostat has a fan switch, set it to ON. See
Fig. 13. After 30 seconds, place your hand in front of an
air register in that zone to check for air flow at the register.
2. Reset fan switch, if provided, to AUTO. After 30 sec-
onds, make sure air flow at register has stopped.

cooling. After 30 seconds (longer, if necessary, for time
delay on control panel), check that air flow at the register

4. Repeat steps 1-3 for each zone thermostat.
When system checkout is complete, return all thermo-
stats to the desired settings for normal system operation.

Before beginning checkout of thermostat operation,
set switches on the control panel for the desired system
operation. See instructions provided with the control panel.
To set up the system for thermostat checkout, adjust
