can be mounted up to 75 feet from the microprocessor inside the
evaporator.
2. Mount the humidity sensor (XH10P) to a discreet side wall location
@ 6ft. from the floor. Bring the two lead wires from the sensor,
and attach to the + and – lead wires indicated. White lead to the
#2 terminal, and Red lead to the #1 terminal on the sensor.
Do not
mount in the air discharge (coil side) of the evaporator.
3. Mount the temp sensor adjacent to the humidity sensor, and run
the lead wires back to the wire harness. It is best to place both
sensors in a location where they cannot be touched by the end
user, and are not in the air discharge of the evaporator.
4. Check supply voltage before connecting to the controller/power
board.
5. Do not expose to water or moisture: use the controller only
Within the operating limits avoiding sudden temperature
changes with high atmospheric humidity to prevent formation
of condensation.
6.
Warning: disconnect all electrical connections before any kind
of maintenance
7. Ensure that the wires for probes leads and the power supply are
separated and are not intertwined or crossed.
XH10P Humidity Sensor
8. The microprocessor has been preprogrammed for 55F°
and 50% RH. To change either setting:
E. Depress the up ^ and down v keys together for more
than three seconds to unlock the keyboard
F. Push the Temp or Humidity Set Key and immediately
Release
18NB1
G. Use the up^ and down v keys to change the value
H. Push the appropriate set key again, and wait 10
seconds
I. Depress the up^ and down v keys to lock the keyboard.
9. There is no reason to change any besides temperature or humidity
set point depending upon the end users preference.

Power to the Evaporator
1. Bring in 14-2 conductor wire with ground to the evaporator, and connect to the 14-2 with ground wire harness
exiting the evaporator. Make sure the line has adequate amp rating for the circuit.
