INSTALLING AND WIRING THE ZP3-HCMS-ESP
WIRING THE TRANSFORMER:
Wire the separate 24 Volt transformer to the
24VAC POWER ‘R’ and ‘C’ terminals. Use
conventional 18-2 thermostat wire. After
removing the outer jacket, strip approximately
1/8” insulation off of each wire. Land each lead to
the 24VAC POWER screw terminals marked C
and R.
TEST, CHECK AND STARTUP:
1. Verify that all component wires have been
connected to the proper terminals and are
secure.
2. Make sure that the selector switches on the
panel are in their proper position.
3. Apply 24 Volt power to the panel.
4. Place all zone thermostats in the OFF mode
with Auto fan.
5. With no calls taking place, the following panel
LEDs should be lit:
24V
LIMIT
ZD1
ZD2
ZD3
6. Visually confirm that all zone dampers are in
the open position.
7. Place zone 1 thermostat in the continuous fan
ON mode and the system blower should come
on. The following panel LEDs should be lit:
24V
G
LIMIT
ZD1
Note: If system static pressure goes above
setpoint, the SPS LED will light along with the
selected non-calling zone LEDs until non-calling
zone dampers modulate to relieve the static
pressure then both LEDs will turn off.
8. Put zone 1 thermostat in Auto fan and repeat
the same steps for zone 2 and zone 3. The only
change in LED status will be ZD2 LED will light
for zone 2 and ZD3 LEDs will light for zone 3.
9. Once the ventilation test is completed, and the
zone thermostat fan modes are set to Auto,
place zone 1 thermostat in the cooling mode and
adjust the setpoint above the space temperature
until it calls for cooling. Keep in mind that the
zone thermostat may have a time delay and that
the panel has a 3 minute short cycle time delay
before allowing the equipment to come on.

Once the cooling cycle is energized, the
following panel LEDs should be lit:
24V
Y1
G
LIMIT
ZD1
10. Repeat the same step for zone 2 and zone
3. LED status should be the same with the
exception that ZD2 LED will light for the zone 2
thermostat cooling test and ZD3 LED will light
for the zone 3 thermostat test.
11. The same test can be done for a heating call
from each zone.
12. Once testing is confirmed, place zone
thermostats in their proper mode of operation.
