Thermostat Heat Anticipator Adjustments. The
initial heat anticipator setpoint should equal the
thermostat’s current amperage draw when the unit is
firing. This setpoint should be measured for the best
results. Use the recommended ranges as a guide. If further
information is needed, consult your thermostat
manufacturer’s instructions.
Recommended Heat Anticipator Setting Ranges:
Fan Time Delay Control
Leads from the time delay controls are factory wired to the
junction box. The fan control is a time delay relay
(approximately 45 seconds ON, 65 seconds OFF). The fan
control is rated at 17 amps.
Notes:
• The start-up fan delay must not exceed 90 seconds
from a cold start.
• For all wiring connections, refer to the wiring diagram
shipped with your unit (either affixed to the side jacket
or enclosed in your unit’s installation instruction
envelope). Should any original wire supplied with the
heater have to be replaced, it must be replaced with
wiring material having a temperature rating of at least
105°C.
Should any high limit switch wires have to be replaced,
they must be replaced with wiring material having a
temperature rating of 200°C minimum.
