Wiring and Setup (all models)
1. Install power wiring and connect to power block or
circuit breakers. In 12, 15 or 20kW models two power
circuits may be used to reduce wiring and breaker
costs as in Figure 14. If a single circuit supply is
desired, install the optional single circuit accessory kit
(P/N 16B0002N02), as shown in Figure 15, that can be
obtained from your distributor.
2.
Ensure unit airfl ow setting is above minimum airfl ow rating
for the electric heat model from Table 1.
3. Check staging jumpers for the application. Typically
only 5 kW (factory setting on all models except 10kW on
20kW models) is needed for fi rst stage electric (W1) to
minimize electric demand. This staging can be adjusted
by moving the staging jumpers as shown in Figure 17.
Whatever is jumped to P1 pin 1 will be energized on
1st stage of electric heat, and P1-2 will be energized as
stage 2 electric heat. See Table C for staging options.
4. Mark the appropriate box of the electric heat model
installed on the additional serial plate on the exterior of
the unit.
5. Turn on the power to the unit and the auxiliary
electric heat.
Auxiliary Electric Heat Start-up
Put thermostat in emergency heat mode in manual mode on
ATC/ACD (see fi gure #) and setpoint to high setting. Unit will
require 15-20 seconds before engaging emergency heat mode
stage 1 (W1) and then another 15-20 seconds to engage
stage 2 (W2) when in ‘Test mode’. Verify proper electric heat
operation. Exit manual mode for normal operation.
