After unit starts running and space gets
warmer, hydronic valve closes and indoor fan
switches off after sixty-second purge time has
elapsed.
3.
After unit starts running and space gets warmer,
adjust thermostat to cooler temperature setting,
hydronic valve closes and indoor fan switches off after
sixty-second purge time has elapsed.
4.
Desired warmer room temperature, adjust
thermostat to warmer temperature setting, which
opens hydronic valve and turns on indoor fan.
5. Desired cooler room temperature, adjust thermostat to
cooler temperature setting. Hydronic valve closes and
indoor fan switches off after sixty-second purge time
has elapsed.
6.
Place thermostat or system switch in
OFF
position. All
operation stops.
NOTICE
Room temperature must be below 85°F (29°C) for
hydronic heater to operate on PTHP's with unit-
mounted controllers.
Hydronic valve is 24Vac normally open valve.
Should power be lost to unit, valve defaults to open
position.
Completion Of Testing For Heat Pumps
Operation testing is complete. If TEST jumper was set to
test mode verify it is set back to normal operation. See
Figure 9, page 17.
Auxiliary Heating Operation — Heat Pump Units
— Outdoor Temperature Below 40°F (4C°) —
Electric Option
1. Place thermostat or system switch in HEAT position.
2. Adjust thermostat to warmer temperature until indoor
fans start running and electric coil starts emitting heat.
3.
After unit starts running and space warms, adjust
thermostat to cooler temperature until electric heater
turns off.
4. Warmer room temperature is desired, adjust
thermostat to warmer temperature setting, which
turns electric heater back on.
5.
Cooler room temperature is desired, adjust
thermostat to cooler temperature setting until
electric heater turns off. Indoor fan switches off after
sixty-second purge time has elapsed.
6.
Place thermostat or system switch in
OFF
position. All
operation stops.
NOTICE
Room temperature must be below 85°F (29°C)
to energize heater on PTHP's with unit-mounted
controllers.
5 kW heat models only — in event limit switch
opens and de-energizes electric heat, reset limit switch
manually;
–
Turn power off
–
Remove control box cover.
–
Locate limit switch.
–
Push reset button in on the face of the switch. See
Figure 12, page 22.
Auxiliary Heating Operation — Heat Pump Units —
Outdoor Temperature Below 40°F (4°C) — Hydronic
Option
1.
Place thermostat or system switch in HEAT position.
2. Adjust thermostat to warmer temperature.
Following occurs:
–
Signal from processor board activates water or
steam valve.
–
Motorized valve opens and allows hot water or steam
to run through coil.
–
Indoor fans run, blowing air through hydronic coil
• Units equipped with Control, indoor fan and
motorized damper operation will be delayed until
hydronic coil reaches 100 ± 5°F (38 ± 3°C).
–
Signal to water or steam valve continues until
room temperature rises above setpoint by 3°F
(2°C).
