ComfortMAX Mode
The ComfortMax exclusive feature is designed to provide automatic system kW/H output sizing
when operated by a single stage thermostat. When using a 2 stages thermostat, the 2nd stage
of the thermostat heat call takes priority. To activate The ComfortMax feature, remove the
jumper wire across W1 and W2 at the thermostat terminals on the furnace control board and set
the ComfortMax switch on the furnace to ON. This will provide automatic kW/H output of the
furnace up to the maximum output of the furnace
.
ComfortMax is a unique feature of the Conforto KHE electric furnace control. Using a single-
stage heating thermostat, the furnace control will determine the ideal number of elements to
engage during each heating cycle. Comfort is maximized by ensuring that the perfect level of
heat is supplied to satisfy the call for heat in regular intervals. On the coldest of days all
available heating elements will be activated, but on those milder days only a few will come on,
thus finding the perfect balance between energy use and homeowner comfort.
The ComfortMax option for heating is selected by a switch on the front panel of the appliance.
When the switch is activated during a call for heat the control will only activate the number of
elements that are estimated to be needed to satisfy the call for heat within a 13 to 18-minute
period.
If the call for heat is satisfied in less than 13 minutes the number of heating elements activated
during the next cycle will be reduce by one. If the last heat cycle has been activated for more than
18 minutes an additional heating element will be energized and this number of elements
will be
energized during the next heating cycle.
If the heating cycle is still not satisfied after 23 minutes then all remaining heating elements are
energized and a further heating element is added to the next heating cycle.
