REMOTE MOUNTING
24 VOLT OPERATION
TWO STAGE CONTROL
1. Disconnect heater from power supply.
2. At the desired location, run the thermostat cable through the hole in the center of the thermostat
mounting sub-base. Leave about three inches of wire for connections. For the correct number of
wires, see appropriate heater or control package wiring diagram and instructions.
3. Attach the sub-base directly to the wall or on a HORIZONTAL outlet box. Level the sub-base with a
spirit level.
4. Connect the wires to the sub-base following the wiring diagram. Complete installation of wiring on
the heater and/or control package. Plug the cable entrance hole to prevent drafts from affecting
thermostat operation.
5. Remove the thermostat cover by pulling up the bottom edge until it snaps free of the locking
springs. Set the heat anticipators to .25 amp. After usage, readjust as needed. The tabs along the
top inside edge fit the sockets on the upper corners of the sub-base.
6. Hang the thermostat on the sub-base and tighten the two captive screws on the thermostat base.
Replace cover by hooking cover tabs into the thermostat base and pushing down until the cover
snaps into the locking springs.
7. Restore power to heater and check for correct operation. The thermostat will, on a fall in space
temperature below its setting, energize the 2 stages of heating in sequence. On a rise in space
temperature towards the stat setting, the sequence is reversed.
