T600HPx-4 and T600HPx-4+PIR Series Heat Pump Thermostat Controllers Installation Instructions

3

Wiring

When an existing thermostat controller is replaced, 
remove and label the wires to identify the terminal 
functions. When a T600HPx-4 or T600HPx-4+PIR 
Series Thermostat Controller is replaced, simply 
remove the old screw terminal blocks and reinsert them 
onto the PCB of the replacement thermostat controller.      

To wire the thermostat controller:

1.

Strip the ends of each wire a 1/4 in. (6 mm) and 
connect them to the appropriate screw terminals as 
indicated in Figure 5.  

2.

Carefully push any excess wire back into the wall. 

Note:

Seal the hole in the wall with fireproof material 

to prevent drafts from affecting the ambient 
temperature readings.

3.

Reinsert the screw terminal blocks onto the PCB.

Note:

If multiple wires are inserted into the terminals, 

be sure to properly twist the wires together prior to 
inserting them into the terminal connectors.

4.

For PIR models, carefully reattach the PIR 
connector to the PCB.

5.

Reattach the thermostat controller cover to the 
mounting base (top side first).

6.

Use a Phillips-head screwdriver to install the 
security screw on the bottom of the thermostat 
controller cover if desired. The security screw 
comes packaged separately in a plastic bag with 
the thermostat controller.  

!

CAUTION: Risk of Electric Shock.

Disconnect power supply before making 
electrical connections to avoid electric 
shock. 

!

CAUTION: Risk of Property Damage.

Do not apply power to the system before 
checking all wiring connections. Short 
circuited or improperly connected wires 
may result in permanent damage to the 
equipment. 

IMPORTANT:

Make all wiring connections in 

accordance with local, national, and regional 
regulations. Do not exceed the electrical ratings of 
the T600HPx-4 or T600HPx-4+PIR Series 
Thermostat Controller.
