5. "Continuous Fan" Feature (Summer Switch)
0.1 The "Continuous Fan" feature will allow the heater
to cycle in a "heat" mode dictated by the controlling
thermostat, even though the fan is operating
continuously.
0.2 Terminals are provided for remote mount of a S.P.S.T.
"Continuous Fan" switch, rated 240V 60 Hz. A jumper
across terminals "T2" and "T3" is installed at the factory,
and must be removed and substituted with the
remote switch leads if this feature is to be available.
Refer to Section B.4 Sample Wiring Schematics - RGX
Series Heater, page 6 to 9.
0.3 A "Continuous Fan" switch may be factory installed
(optional feature) directly in the heater.
6. Fan Delay
0.1 All heaters incorporate a fan delay feature in both
"ON"
the
allowing the heater to come to temperature before the
fan operates (no cold blasts) and to cool down in the
"OFF"
cycle (longer life for the control components and
motor). Delay
is 20-70 seconds.

7. Remote Energy Management Control
0.1 Remote energy management control is standard on
40 kW and 50 kW units. Internal power to contactor
coil C2 may be interrupted and controlled remotely
by removing the jumper between terminals "T2"
and "T3", and then connecting a passive contactor
in its place. A closed contact will allow 100% heating
capacity and an open contact will allow 50%
heating capacity. Refer to Section B.4 Sample Wiring
Schematics - RGX Series Heater, page 6 to 9.
8. Final Inspection
