ELECTRICAL ELEMENT INSTALLATION – WOOD-ELECTRIC MAX CADDY (OPTIONAL)
The high limit control is a manual reset thermostatic sensor that is located inside the electrical unit. The electric unit
must be connected as shown on the diagram (see WIRING DIAGRAM). The connections must conform to the
diagram.
Electrical connections must conform to the wiring diagram supplied with the option.
The wood / electric combination model uses two thermostats: one thermostat controls the electric heating, and 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. 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.
Therefore, under normal wood-electric combination use, you should set the wood system thermostat 2
o
to 4
o
higher
than the electric system thermostat. The bigger the gap, the more the wood heating will contribute to the overall
heating needs.
If the temperature of the electric unit exceeds the high limit , the thermostatic sensor will disengage the elements.
To reactivate, press the red “manual reset” button on the thermostatic sensor ( L-170 Thermodisc) after finding and
fixing the problem that has caused the unit to overheat (static pressure too high, fan breakdown, etc.)
