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.
