Note: All inputs require 24VAC (ungrounded side) power to operate and a 24V COM
common connected.
THERM and U1 - Connection terminals for the tank thermistor sensor used in the DHW control mode.
Only one should be connected at a time.
U2 - Connect to the CN27 Water Tank Temp input on main board or the cable marked “Water Tank”.
CN31 - Connect to CN31 input on main board using the supplied cable.
CN35 - The heat pump main board ships with a factory installed jumper wire on CN35. This jumper will
create a continuous heating mode enable signal and the heat pump will maintain the inlet water heating
set point whenever the heat pump is powered unless there is a cooling or DHW demand. To operate
the heat pump only when there is a 24V demand supplied to the I/O board, remove the main board
jumper and connect CN35 on the I/O board to CN35 on the main board with the supplied cable.

Relay Board I/O Description

Note: All inputs require 24VAC
(ungrounded side) power to operate and
a 24V COM common connected.
DHW - Supplying 24V to the DHW
terminal will enable HP DHW (Hot
Water) mode. When DHW mode is
enabled the heat pump will monitor the
temperature of the connected external
temperature sensor. Regardless of the
other heating or cooling demands
present, when the temperature of the
sensor drops below the DHW mode set
point plus the set differential the heat
pump will activate it’s the three way valve
output and start in heating mode. The
unit will cease operation when the sensor
reaches the set point temperature, and the
heat pump will again monitor other
cooling or heating demand calls. The
DHW mode can be used as a secondary
heating mode with its separate
temperature set point and priority over
other demand calls.
HEAT - Supplying 24V to the HEAT
terminal will enable HP Heating mode.
When Heating mode is enabled the heat
pump will monitor the temperature of the
inlet water temperature sensor. When the
temperature of the sensor drops below
the Heating mode set point plus the set
differential, the heat pump will start in
heating mode. The unit will cease
operation when the sensor reaches the set
point temperature.
COOL - Supplying 24V to the COOL
terminal will enable HP Cooling mode
and switch the COOL isolated relay
contacts. When Cooling mode is enabled
the heat pump will monitor the
temperature of the inlet water
temperature sensor. If there is no 24V
input on the HEAT or DHW terminals,
then when the temperature of the sensor
rises above the Cooling mode set point
plus the set differential the heat pump
will start in cooling mode. The unit will
cease operation when the sensor reaches
the set point temperature, or when a
HEAT or DHW demand is present.
CL PRI - Supplying 24V to the CL PRI
terminal will enable HP Cooling mode
even if a HEAT call is present and switch
the COOL isolated relay contacts. When
Cooling mode is enabled the heat pump
will monitor the temperature of the inlet
water temperature sensor. If there is no
24V input on DHW terminals, then when
the temperature of the sensor rises above
the Cooling mode set point plus the set
differential the heat pump will start in
cooling mode. The unit will cease
operation when the sensor reaches the set
point temperature, or when a DHW
demand is present.
WH - Supplying 24V to the WH terminal
has no effect on the heat pump. It
produces a 24V output on the WH LW
output terminal anytime there is no
DHW call and switches the WH LOW
isolated relay contacts. If there is 24V on
the DHW terminals than the voltage is
instead routed to the WH HI output
terminal and switches the WH HIGH and
WH LOW isolated relay terminals.
AHP - Supplying 24V to the AHP
terminal has no effect on the heat pump.
It produces a 24V output on the AHP
output terminal except when there is both
a COOL or CL PRI input and a DHW
input. This allows the control voltage to
an air handler circulator pump relay to be
disconnected when the unit is operating
in cooling mode in the case of a DHW
call being activated which will override
the cooling call.

DHW - Supplying 24V to the DHW terminal will
enable HP DHW (Hot Water) mode. When DHW
mode is enabled the heat pump will monitor the
temperature of the connected external temperature
sensor. Regardless of the other heating or cooling
demands present, when the temperature of the
sensor drops below the DHW mode set point plus the

unit will cease operation when the sensor reaches the
set point temperature, and the heat pump will again

HEAT - Supplying 24V to the HEAT terminal will
enable HP Heating mode. When Heating mode is
enabled the heat pump will monitor the temperature
of the inlet water temperature sensor. When the
temperature of the sensor drops below the Heating
mode set point plus the set differential, the heat pump
will start in heating mode. The unit will cease
operation when the sensor reaches the set point
temperature.
COOL - Supplying 24V to the COOL terminal will
enable HP Cooling mode and switch the COOL
isolated relay contacts. When Cooling mode is
enabled the heat pump will monitor the temperature
of the inlet water temperature sensor. If there is no
24V input on the HEAT or DHW terminals, then when
the temperature of the sensor rises above the Cooling
mode set point plus the set differential the heat pump
will start in cooling mode. The unit will cease
operation when the sensor reaches the set point
temperature, or when a HEAT or DHW demand is
present.
CL PRI - Supplying 24V to the CL PRI terminal will
enable HP Cooling mode even if a HEAT call is
present and switch the COOL isolated relay contacts.
When Cooling mode is enabled the heat pump will
monitor the temperature of the inlet water
temperature sensor. If there is no 24V input on DHW
terminals, then when the temperature of the sensor
rises above the Cooling mode set point plus the set
differential the heat pump will start in cooling mode.
The unit will cease operation when the sensor
reaches the set point temperature, or when a DHW
demand is present.
WH - Supplying 24V to the WH terminal has no effect on the heat pump. It produces a 24V output
on the WH LW output terminal anytime there is no DHW call and switches the WH LOW isolated
relay contacts. If there is 24V on the DHW terminals than the voltage is instead routed to the WH HI
output terminal and switches the WH HIGH and WH LOW isolated relay terminals.
AHP - Supplying 24V to the AHP terminal has no effect on the heat pump. It produces a 24V output
on the AHP output terminal except when there is both a COOL or CL PRI input and a DHW input.
This allows the control voltage to an air handler circulator pump relay to be disconnected when the
unit is operating in cooling mode in the case of a DHW call being activated which will override the
cooling call.
