Operating the 3-Zone Override Module
1. The module is marked with three separate zones: Zone 1, Zone 2 and Zone 3. These zones
correspond to the relays in the transceiver. To enable the override module, press the Override
Start/Stop rocker switch once. The green indicator “Override On” light will illuminate.
2. To activate the override of a zone, press the zone(s) rocker switch(es) to the “Enable” position.
NOTE: Zone 1, 2 or all three can be enabled at the same time in any sequence. The light on the
3-Zone Override Module corresponds to LED4 in the Transceiver.
3. To deactivate the override of a zone, press the zone(s) rocker switch(es) to the “Disable” position. The
override period can be cancelled by pressing the Override Start/Stop rocker switch again.
Testing the 3-Zone Override Module
1. Initiate a peak mode. Check voltage between T1 and L2 positions of the main wiring terminal block on
those circuits connected to the override. There should be no voltage present on any of the circuits.
2. Activate the override by pressing the Start/Stop rocker switch once. Press the rocker switch for Zone 1
to the “Enable” position.
3. Test voltage between T1 and L2 positions of the main wiring terminal block on those circuits connected
to Zone 1 Override. There should be a voltage reading. Press Zone 1 rocker switch to the “Disable”
position.
4. Follow steps 1-3 to test voltages of those circuits connected to Zone 2 and Zone 3 of the override as
well.
CHECK OUT PROCEDURES
CHECK OUT PROCEDURE FOR TRANSMIT MODE
1. Turn power on to the transceiver.
2. Look at LED-L3, (1). It should blink OFF-and-ON at a rate
based on the outdoor temperature.
3. Look at LED-L4, (2). It may be:
• OFF when receiving an off-peak signal
• ON solid if an override switch is enabled
• blinking OFF and ON according to the type of signal being
received from the control device.
4. Simulate an off-peak period.
• If DIP switch #1 is in the ON position, this can be done by
placing a jumper wire across the R and P terminals.
• If DIP switch #1 is in the OFF position, an open across R
and P will simulate the off-peak period.
5. LED-L4 should be OFF and the relay LED’s should all be ON.
6. Make sure PLC signal is received by each controlled device:
transceiver receiver, Steffes Heating Systems Electric Thermal
Storage (ETS) heater, receivers, and all other controlled loads.
7. Simulate a peak period.
• If DIP switch #1 is in the OFF position, this can be done by
placing a jumper wire across the R and P terminals.
• If DIP switch #1 is in the ON position, an open across R and P will simulate the peak period.
• Look at the relay LED’s. They should all be OFF.
8. Look at LED-L4. It should be blinking at the peak rate as shown for Peak (P) Signal.
