When the temperature in your house will go below the value at which your wall thermostat is programmed, a signal
will be sent to your furnace through the PC board, activating the motorized damper located in front of the furnace
and allowing more oxygen to the fire. The RTD (temperature sensor), located in the hot air plenum of your furnace,
will read the plenum temperature. When the temperature reaches the start-up value selected by the user (KIP), the
blower will start functioning at the speed selected by the user. If the temperature exceeds the limit determined by the
manufacturer, the blower will automatically select the maximal speed and the front air damper will close in order to
slow down combustion. When the temperature returns to a safe level, the blower will return to the speed selected by
the user.
Programming
Make sure that your wall thermostat is well connected to the PC board. Make sure that the right port has been
selected based on the type of thermostat (e.g. 24VAC or Millivolt).
In the MODE menu, select MANU by pushing the SELECT button. Then, using the arrows buttons, choose from the
different selections: KIP, TEMP, UNIT, or FAN. Consult the “Selections” section in order to obtain a compete
definition of the terms KIP, TEMP, UNIT, and FAN.
When your choice is made, press SELECT. Then, use the arrows to make the appropriate adjustment. Press
SELECT to memorize your adjustment. To change the selection ( KIP, TEMP, UNIT, or FAN) push an arrow
button. To go back to the main menu (HEAT, COOL, CIRC, MANU), push on the MODE button. After two minutes
of inactivity on the keyboard, the display will shut itself off.
4.5.7 The Selections
KIP (Kick-in Point - start-up temperature of the furnace blower)
Using the arrows, increase or decrease the temperature at which the furnace distribution blower will start
functioning. You can adjust the temperature between 107°F (42°C) à 132°F (56°C) . After two minutes of inactivity
on the keyboard, the display will shut itself off. The KIP must be programmed if the furnace is operated under the
HEAT or MANU modes.
TEMP (Temperature)
By pushing the arrows, you will see the current temperature inside the main hot air plenum of your furnace. After two
minutes of inactivity on the keyboard, the display will shut itself off. The TEMP selection has no impact on the
operation of the furnace. It is offered as a practical way for an installer or a technician to quickly obtain the
temperature inside the hot air plenum under the HEAT or MANU modes if a problem arises and the temperature
must be known in order to trouble shoot the furnace.
UNIT (measuring unit)
By pushing the arrows, you will select the measuring unit that you wish to use (Fahrenheit or Celsius). Thereafter,
temperatures will be displayed according to your selection. After two minutes of inactivity on the keyboard, the
display will shut itself off. The UNIT selection has no impact on the operation of the furnace. It is simply a
preference chosen by the technician or the user of the product..
FAN (blower speed)
Using the arrows, increase or decrease the blower speed. You can choose from six preselected speeds. This
selection is very important for the modes COOL, MANU, or CIRC. There is a choice of 6 different speeds. Under
the COOL mode, the speed selected is the speed at which the distribution blower will work when a cooling demand
will be sent by the thermostat. Under the MANU mode, it is the speed at which the distribution blower will work
