Hvac ZP4-ESP, Installation Manual

Page: 11 / 14

BALANCE POINT ADJUSTMENTS:
When used with a heat pump or dual fuel system and fitted with a
ZPA-OTS outdoor sensor, the panel can provide both high and low
balance point control.
High Balance Point - The panel has a potentiometer marked HI BAL
PT that is adjustable from 20° to 60° F. If the outdoor temperature
rises above the high balance point setting, the panel will prevent
auxiliary heat from coming on.
Note: If a zone thermostat is set in the emergency heat mode, the
panel will override the high balance point setting regardless of the
outdoor temperature and the system will function in emergency heat
until the thermostat is taken out of the emergency heat mode.
Low Balance Point - The panel has a potentiometer marked LO BAL
PT that is adjustable from 0° - 40° F. If the outdoor temperature falls
below the low balance point setting, the panel will lock out
mechanical heating and change over to the auxiliary heat source.
ZONE BYPASS
Each zone has a Zone Bypass jumper that can be used to remove
the ESP function for that zone. This can be useful in applications
where one zone out of three or four zones may represent a very small
percentage of the total system CFM.
