11.4.3. AUXILIARY HEAT SOURCE PRIORITIZATION
If you have configured one or many auxiliary heating sources (electrical element, heat pump, oil), you must choose the
priority order when there is a heating demand. If, for example, the wood no longer provides sufficient heat, the auxiliary
heating selected in priority one will take over. If priority one no longer provides enough heat, or does not provide it fast
enough, priority 2 will take over. Heating priorities are chosen in the "MAIN" menu, under the "SETUP" option. Select
"OPTIONS" and "CONFIGURATION". Use the arrows to select the priority order.
11.4.4. EXTERNAL TEMPERATURE PROBE
It is possible to connect an external temperature probe on the Max Caddy. This temperature probe is used primarily to
reduce electricity consumption and reduce the bill by prioritizing the transition to an auxiliary heating source when it is
too cold outside or when it is the overcharging billing period (peak usage) depending on the electricity supplier.
HEAT PUMP : With a combination wood, electrical component and heat pump you can set your temperature probe to
not use your heat pump when it is too cold and the coefficient of performance becomes too low. (Electrical element
should be prioritize during configuration the outdoor temperature probe.)
When the temperature probe is functioning, the « ECO » mode will show on the main page.
11.4.4.1.
"BI-ENERGY" FUNCTION
The bi-energy function is used when a local utility company (Hydro-Quebec for instance) offers a bi-energy program
under which a preferential rate is given, provided that the appliance is equipped with an electronic control that
guaranties the use of a particular source of energy (ex: electricity) based on a given criterion (ex: the outdoor
temperature).
When the MAX Caddy is programmed for bi-energy, the temperature probe (normally open contact) is connected to the
OUTDOOR PROBE
PC board (See Section 28.2 -
).
The contact remains open for as long as the outside
temperature is above a certain value (this reference value is programmed into the system provided by the utility
company). As long as the contact remains open, the electrical unit supplies the heat when the wood is not able to
satisfy the thermostatic demand. If, however, the outside temperature reaches a level below the reference value, the
contact closes and the oil unit is used as the option for heat if the wood is not able to satisfy the thermostatic demand.
