To wire a heat pump or electric heater.
1.
At the Power Center, install the relay into the high voltage compartment. Plug control
wire into the EHTR relay socket on the Power Center circuit board.
2.
Run a 2-conductor cable the from heater to the Power Center.
3.
At the heater, cut thermostat wire and connect to 2-conductor cable.
4.
At the Power Center, connect 2-conductor cable to LINE 1 and LOAD 1 of the relay
terminal block.
Solar Heating
Solar systems require the following additional equipment, a Solar Temperature Sensor (model
TS-5L), a Valve Actuator (model CVA-24T), and a solar valve (model SOL-2T).

To install solar equipment
1.
Discard clamp included with sensor kit. For unglazed panels, fasten sensor next to solar
panels. For glazed panels, suspend sensor between collector and glazing.
2.
Run a 2-conductor cable from the sensor to the Power Center.
3.
At the sensor, use crimp connectors (included) to provide waterproof connections. Before
making connections, cut off stripped ends of cable. Insert the 2 wires to be connected into
the connector and squeeze the connector with a pair of pliers. Two extra connectors are
included.
Caution Do not strip wires.
4.
At the Power Center circuit board, connect sensor wires to the SOL SENS screw
terminals. Pay attention to color-coding of wires.
5.
Turn on SYST SOLR configuration switch located at the bottom of the Power Center
circuit board.
6.
Connect solar Valve Actuator cord into AUX VLV socket at the Power Center circuit
board.
Note Infield calibration of Solar Temperature Sensor is required. See Calibration for details.
Solar Booster Pump Control
If a solar booster pump is being used, install relay kit (model RLY-LX) into Power Center. Plug
control wire of relay into SOL PMP relay socket.
