Determine whether the fan operates during heating and cooling
modes. If these checks fail to reveal a problem and the unit will not
operate, contact a trained service technician for proper diagnosis or
call the factory service department for assistance.
eUnit-mounted thermostat
1.
Use the system switch to place the Water Source Console Units in
either the "COOL", "HEAT", or "OFF" position (see Figure 12).
Test operation in all positions.
2.
Use the fan speed switch places the fan in either LOW or HIGH
speed (see Figure 12). Test operation in both positions for heat-
ing and cooling.
3.
Test operation of the optional Fan Cycle switch (this is a toggle
switch on side of control box), with switch set at ON (continuous
fan operation) or AUTO (cycling with thermostat) for both heat-
ing and cooling. Set the switch in the desired position.
4.
Rotate the thermostat knob counter clockwise to increase setpoint
temperature, or clockwise to decrease (see Figure 12). Turning
the unit-mounted thermostat knob counter clockwise until it
stops will produce the warmest room temperature, while turning
it clockwise until it stops will produce the coolest. The setting can
be adjusted for personal comfort.
Boilerless control operation-Optional
•
For Heat pump units with an optional Boilerless control and
electric heat, the heat pump and electric heat do not operate
simultaneously.
•
The Boilerless control will monitor incoming water temperature
to the heat exchanger and when it drops below approximately
50°F the control will change from heat pump operation to
electric heat.
CAUTION
DO NOT rotate the thermostat knob back and forth from
heating to cooling. This causes the compressor to cycle on and
off rapidly and will cause damage to the compressor. Allow
the compressor to remain off for at least three minutes prior to
restarting the unit.

Remote-mounted thermostat
1.
Use the thermostat to place the Water Source Console Unit in
either the "COOL", "HEAT", or "OFF" position. Test operation
in all positions.
2.
If the thermostat is fitted with a
the fan in either "ON", "OFF", or "AUTO". Test operation in all posi-
tions.
3.
Check thermostat calibration for both heating and cooling op-
eration.
Straight cooling Water Source Console Units
Cooling cycle
1.
Place the thermostat or system switch in the COOL position.
2.
Adjust the thermostat to a cooler temperature until the indoor fan
starts running. The compressor should then turn on and cold air
will begin to flow from the unit. Let the unit continue operating to
cool the room and remove humidity.
3.
After the unit starts running and the space gets cooler, adjust the
thermostat to a warmer temperature until the compressor cycles
off.
4.
If a colder room temperature is desired, adjust the thermostat to a
cooler temperature setting, turning the compressor and fan back
on.
5.
If a warmer room temperature is desired, adjust the thermostat to
a warmer temperature setting, the compressor will stop.
6.
Place the thermostat or system switch in the OFF position.
All operation should stop.
