Electric Unit - PSG Caddy PF01010 Installation And Operating Instructions Manual

3.3.4.3 ELECTRIC UNIT

The wood/electric combination model uses two wall thermostats; one controls the
electric heat and the other one the wood heat. In this configuration, the electric
heat has priority over the wood.
Whenever there is a call for heat from the electric thermostat, the air intake
damper closes, the blower kicks on and the electric elements turn on in
sequence of 4 to 5 kW at a time.
When the demand for electric heat is satisfied, the wood system will be
reactivated if the wood thermostat is set higher than the electric thermostat.
In normal wood/electric operation, the wood thermostat should be set slightly
higher (3°C or 5°F) than the electric thermostat to allow the wood furnace to
stabilize the temperature before the electric thermostat calls for heat. The bigger
the increment, the more wood will contribute to the global heating needs.
This furnace's blower uses a four speed motor; one speed (LOW) is controlled by
the manual switch for summer operation. Three heating speeds are available
(MED-LOW, MED-HIGH AND HIGH) and will be selected according to the duct
size and the needs for ventilation.
If the temperature in the electric unit reaches 170°F, the L-170 disc control will
cut the power to the elements and it will have to be reset manually. Find and
correct the cause of overheating before reactivating the unit.
