12. REMOTE OPERATION
The heaters are equipped to work with external remote
controls. The unit can be connected to either a toggle
switch or the switch contacts of a third party remote. The
remote works by either making or breaking the circuit
created by the remote wiring.
Typically, a remote does not supply power to the heater,
heater. If your remote is supplying its own voltage to the
heater, it will not work with this heater and may damage
the digital circuit board.
Important installation notes for remote or external wiring
• Remote wiring must be run in a separate conduit.
• Remote wiring must not be run parallel to high
voltage lines.
• For runs of under 30 ft. (9 m), remote wiring
should have stranded conductors with a minimum
of 22 AWG, 600V, cable twisting 1.5" to 2.5"
(38 mm to 64 mm) lay and jacketed.
• For runs over 30 ft. (9 m), the conductors should be a
minimum of 20 AWG, 600V, cable twisting 1.5" to 2.5"
(38 mm to 64 mm) lay that is shielded and jacketed.
• Maximum cable length is 200 ft. (61 m).

Supplied Wires for the Remote Interface Harness
1. Turn on power to the heater.
2. For a remote control without its own sensor, set the
desired set point, for example 102°F (39°C).
3. For a remote control with its own sensor, set the
temperature to the highest setting available on the
control on the heater. The actual set point will be
controlled by the remote control.
4. Turn off and remove power from the heater.
5. On the "Remote Interface Harness", the supplied
two wires provide power out to either a toggle
switch or the switch contacts of a third party remote.

NOTE:
heat until the master control is CFH.
