ELECTRONIC OVERRIDE MODULES (OPTIONAL)
The Steffes Override Modules are optional devices that allow
the use of a normally controlled device, such as a water heater,
during a peak control time (power company permitting). Either
override timer will allow for an override of the relays. The
override duration is 90 minutes (1.5 hours). It can be cancelled
anytime during the cycle.
There are two electronic override controls available to use with
the transceiver. The push-button override switch, (1), and the
three zone override module, (2).
PUSH-BUTTON OVERRIDE SWITCH
1.
When using the push-button override switch,
connect the two purple override wires to the OVR
and OVS terminals on the transceiver board’s low
voltage terminal block.
2.
Connect a jumper wire from OVC to OV1 to
override relay #1 and/or from OVC to OV2 to
override relay #2.
NOTE: Refer to the Relay Operation section for
more information on which relays will
utilize the various override inputs.
3-ZONE OVERRIDE MODULE
1.
Mount the module into a 2-gang box anywhere in the structure where it will be convenient for the user
to access.
2.
If using the 3-zone override module, remove applicable transceiver knockout(s) from the bottom of the
enclosure below the low-voltage connection area.
3.
Connect wires to low-voltage terminal circuit connection points to match circuit leads marked on
override module circuit board (OVS to OVS, OVR to OVR, etc.). Tighten terminal screws securely.
4.
The module contains five (5) low
voltage wires: 3 purple, 1 yellow, 1 red,
and 1 orange/black. Splice 18/6 low
voltage wire to these wires and route
them through the low voltage raceway
compartment in the transceiver.
5.
Using only line voltage rated wire inside
the transceiver, connect the override to
the low voltage terminal strip in the
transceiver as follows:
Purple wires connect to OV1, OV2,
OV3, or OV4 terminals
Red wire connects to OVR terminal
Orange/black wire connects to OVS terminal
Yellow wire connects to OVC terminal
6.
Label each override zone on the module and in the relay panel (inside, on the front cover label).
7.
Install the front cover on the transceiver and energize the system.
