8.2 MAIN WALL CONTROL
The only main wall control compatible with this unit is the X-Touch. Only one main wall control can be installed for each unit.
Proceed as follows to connect the main wall control cable to the 4-position terminal block:
1. Strip the end of the cable.
2. Strip 1/4 off the end of the 4 wires. Do not strip longer than required.
3. Using a small flat blade screwdriver, connect each wire to its corresponding
terminal by referring to the labels on the unit (YELLOW to Y; BLACK to B; RED
to R; GREEN to G).
4. Reinstall the terminal block on the electronic board.
9. ELECTRICAL CONNECTION TO THE FURNACE
WARNING
Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low
voltage class 2 circuit of the furnace blower control.
For a furnace connected to a cooling system:
On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” at the thermostat and
thereby turning on the cooling system. If you identify this type of thermostat, you must use the ALTERNATE FURNACE INTERLOCK WIRING.

11. BALANCING THE UNIT
11.1 B
EFORE STARTING
What you need to balance the Unit:
One X-Touch main wall control close to the unit.
A magnehelic gauge capable of measuring 0 to 1 inch of water (0 to 250 Pa) and 2 plastic tubes.
The balancing chart and preset speeds table of the unit; affixed on the unit, behind the small control panel.
Before balancing the unit:
Seal all the unit ductwork with tape. Close all windows and doors.
Turn off all exhaust devices such as range hood, dryer and bathroom fans.
Make sure all filters are clean (if it is not the first time the unit is balanced).
NOTE: Make sure that the furnace/air handler blower is ON if the installation is in any way connected to the ductwork of the cold air
return. If not, leave furnace/air handler blower OFF.
Installing the magnehelic gauge:
1. Place the magnehelic gauge on a level surface and adjust it to zero.
2. According to the airflow to be measured, connect tubing from gauge to STALE
air flow or FRESH air flow pressure taps (see illustration at right).
3. Be sure to connect the tubes to their appropriate high/low fittings. If the gauge
drops below zero, reverse the tubing connections.
Balancing Chart and Preset Speeds Table
Use the balancing chart on the unit to convert pressure (in. w.g.) values read by the magnehelic gauge to airflow (CFM) values. While
balancing, the X-Touch wall control screen shows which pressure taps have to be used. Keep in mind that a difference between flows up
to ±10cfm is acceptable. See example below.
