Repeat this procedure for the remainder of the heat
circuits and hot water heater(s). Heat circuits are
normally on 20 Amp circuit breakers and require #12
AWG wire. Hot water heaters are normally on a 30
Amp breaker and require #10 AWG wire. All Energy
Sentry relays are equipped with #10 AWG Red lead
wire.

14.1
Turn off dryer circuit breaker.
14.2
The dryer is connected to the breaker panel as
shown in Figure 8. Both wires are connected to a
30 Amp, 240 VAC double pole breaker.
14.3
The relay is inserted in series on the heating element
side of the load only, as shown in Figure 8. The motor
of the dryer is not connected. Care must be taken to
insure that the dryer is connected properly since
improper connection may damage the dryer.

This schedule may be altered as necessary to suit the needs of the particular home and user. This is an example only.
Your situation may be different. For assistance contact your Energy Sentry
representative. Circuits with compres-
sors must have minimum off and minimum on times programmed in. See Section 17 for system programming
procedure.

Remove either one of the two wires from the load's breaker,
and wire-nut this lead to a short length of #10 or #12 AWG
(depending on load size) wire which runs into the Relay
unit. Wire-nut this length of wire to one lead of the relay’s
contact. With another short length of the appropriately
sized wire, wire-nut it to the other lead of the relay’s
contact. Connect the other end of this short length of wire
back to the circuit breaker’s terminal where the wire was
originally removed as shown in Figure 7.
