CADDY WOOD/ELECTRIC
The high limit control is a manual reset thermostatic captor that is located inside the electric unit (see
WIRING
DIAGRAMS
). The electric unit must be connected as shown on the diagram. Install the wood fan limit control on
the support provided, at the determined location. The connections must conform to the diagram.
Install the damper with the bracket included at the right location. Install the damper motor on the right side of the
façade above the door (use the pre-drilled holes). The chain that links the air inlet damper to the motor must have a
play of 1/8 in. When there is no call for heat, the air inlet damper must be completely closed and the chain must be
affixed to the damper motor at the “8 o’clock” position.

ELECTRIC ELEMENT CADDY WOOD / ELECTRIC
The WOOD / ELECTRIC combined model uses two thermostats: one thermostat controls the electric heating, the
other one controls the wood heating. With this system, the electric heating has priority over the wood heating.
When the thermostat activates the electric heating, the air inlet damper closes down (if opened), the blower starts
and the electric elements are successively activated per block of 5 kW. The system may be equipped with an
outdoor sensor (not included) which will allow the last block of elements (5 kW) to start up only when the outside
temperature is cold enough. This will reduce the power of the systems by 5 kW during mild temperature for more
comfort and economy.
When the call for electric heating is satisfied, the wood system will take over if the starting point of the wood
system thermostat is superior to that of the electric system so, in normal bi-energy use, you should set the wood
system thermostat 2
o
to 3
°
C. higher than the electric system thermostat; the bigger the gap, the more the wood
heating will contribute to the overall heating needs.
Take note that this furnace is equipped with a four speed blower motor. Aside from low speed, you may select
medium-low, medium-high or high speed.
If the temperature of the electric unit exceeds the high limit , the thermostatic captor will disengage the elements.
To reactivate, press the red “manual reset” button on the thermostatic captor ( L-170 Thermodisc) after finding and
fixing the problem that has caused the unit to overheat (static pressure too high, fan breakdown, etc.)
