Step 4

1.For TK-6 Thermostat kits, wire one blue lead of thermostat to terminal block pole “L1” and the other blue lead to terminal block pole “L2”. Connect incoming power wiring to the black leads with wire nuts provided by others. See figure 4 for line voltage thermostat. See figure 8 for control voltage thermostat.

For TK-5 thermostat kits with an internally provided control circuit, remove white jumper wire on terminal block between poles “C1” and “C2”. Connect blue wire of thermostat to pole “C1” and black wire to “C2”. See figures 5, 6 or 7.

For TK-5 thermostat kits with an externally provided control circuit, remove white jumper wire on terminal block between poles “C2” and “C3”. Connect blue wire of thermostat to pole “C2” and black wire to “C3”. See figure 7.

2.Inspect wiring to make sure it matches the appropriate wiring diagram.

3.Close heater cover and reattach screws.
