24 WSV6 Vertical Series – IOM
ELECTRICAL
HIGH VOLTAGE
Disconnect all power supplies before servicing. Lock
out/tag out to prevent accidental electrical shock. NOTE:
There may be multiple power sources supplying the unit.
Use copper conductors only. Install all parts and panels
before operation of unit. Failure to follow these warnings
can result in injury or death.
All wiring must comply with local and national code
requirements. Units are provided with wiring diagrams and
nameplate data to provide information required for
necessary field wiring.
The WSV6 water source heat pumps are provided with a
class 2 transformer for 24VAC control circuits. Should any
add-on accessory or component also have a class 2
transformer furnished, care must be taken to prevent
interconnecting outputs of the two transformers by using a
thermostat with isolating contacts.
Connect ground wire to ground terminal marked “GND”.
Failure to do so can result in injury or death.
Any device that has been furnished by the factory for field
installation must be wired in strict accordance with the
associated wiring diagram. Failure to do so could damage
components and void warranties.
208-230 VOLT OPERATION
All 208-230 Volt units are factory wired for 230 Volt
operation. For 208 Volt operation,
moving/changing/rewiring the line voltage tap on the
24 Volt control transformer is required. See note 3 on the
wiring diagram for instruction.
LOW VOLTAGE
THERMOSTAT
A standard 24 VAC Heat Pump thermostat is required that
will operate the reversing valve in the cooling mode.
Thermostat connections and their functions are below in
FIGURE 13 – Thermostat Connections as follows:
C – Transformer 24VAC Common
O – Reversing Valve (energized in cooling)
Y – Compressor Contactor
R – Transformer 24VAC Hot
G – Evaporator Blower
FIGURE 13 – Thermostat Connections
THERMOSTAT INSTALLATION
The Thermostat should be located on an interior wall in a
larger room, away from supply duct draft. Position the
thermostat back plate against the wall so that it appears
level and so the thermostat wires protrude through the
middle of the back plate mounting holes and drill holes
with a 3/16” (5mm) bit. Install supplied anchors and secure
plate to the wall. Thermostat wire must be 18 AWC wire.
