DIP switches 2, 3, 4, and 5 are used to select the channel on which the transceiver will transmit (send signal). There are 15 channels available. Only one transceiver is required per distribution transformer. If multiple transceivers in the transmit mode are installed on a single distribution transformer, they must be set to different channels. Select a channel and set DIP switches 2-5 according to the chart below:

* Steffes 1000 and 2000 Series room heating units receive only on “slow” speed channels (Channels 1 or 2 as set from the factory or on channels 12/13 or 14/15 with a software upgrade). Slow channels transmit a signal every 3-4 minutes, so can take up to 7-10 minutes for a receiver to receive. Fast channels transmit every minute, so it generally only takes 2-3 minutes to receive.
** The Steffes transceiver transmits a signal over the power lines constantly unless set to one of the intermittent transmit channels shown above. If the power company’s control device is power line carrier (PLC) such as those manufactured by Cooper Power System/Cannon Technologies, the transceiver must transmit intermittently to allow the power company’s control device to operate properly. When set to transmit intermittently, the Steffes Heating systems will display a lower-than-normal percentage of good packets received.
