PANEL SETUP
CONFIGURING PANEL FOR EQUIPMENT APPLICATION:
Once all wiring is completed, the panel can be configured for the specific equipment application.
The ZP4-ESP has a row of slide switches located on the printed circuit board along with a switch
selection chart.
SWITCH DEFINITIONS:
SW-1
Select type of HVAC equipment.
Right = Conventional Heat/Cool
Left = Heat Pump
SW-2
Selects type of heat pump system.
Right = Conventional heat pump
Left = Heat pump with fossil fuel furnace
SW-3
Selects heat pump reversing valve order.
Right = O (energizes in cooling)
Left = B (energizes in heating)
SW-4
Selects fan operation .
Right = Fan controlled by furnace
Left = Fan energized on call for heat
SW-5
Purge option
Right = No purge after call
Left = Purge after call is satisfied for 1
minute into last zone calling before all
dampers go open
SW-6
Capacity Control option
Right = No Capacity Control
Left = Only allow additional equipment
staging if 2 or more zones are calling and at
least one zone is calling for an additional
stage
LIMIT ADJUSTMENTS:
High Limit -
The panel has a potentiometer marked HI LIM that is
adjustable from 100° to 180° F. When used with the ZPA-DTS duct
sensor, should the temperature rise above the high limit setting, the
panel will shut off the heating system. The fan will continue to run until
the temperature drops below the high limit setting. The high limit
setpoint should always be below the internal safety limit setting of the
heating system.
Low Limit -
The panel has a potentiometer marked LO LIM that is
adjustable from 30° to 55° F. When used with the ZPA-DTS duct
sensor, should the temperature fall below the low limit setting, the
panel will shut off the compressor. The fan will continue to run until
the temperature rises above the low limit setting. A time delay will also
be initiated to prevent short cycling of the equipment.
