RCS TR16 Thermostat

Operational Note:


Regarding the RCS TR-16 thermostat….

The TR-16 Wall Display Unit (2-digit User Interface) doesn’t allow you to program a schedule into the RCS Control Unit. BUT the RCS Control Unit does have the ability to run a schedule.

If an automation controller connected to the Control Unit sends the command to run a schedule, the default schedule or whatever schedule that might be programmed into the Control Unit will become active.

Be aware that the M1 sends this command when the “HOLD” is turned off (the opposite of “hold” is “run” to the RCS). The HOLD can be turned on and off by either by a Rule, or ELK-RM, or the Virtual Keypad.

If a RCS TR-16 thermostat changed its’ setpoint automatically at a time during the day that it should not have…

1.) Check any rules for thermostats that would turn the “HOLD” off. Delete the HOLD OFF statement or change it to HOLD ON.

2.) If they use ELK-RM or Virtual Keypad, make sure that the HOLD button is ON and that they should remember to never play with that button again.

Had a M1 customer that had two RCS TR-16 thermostat heads on the RCS RS485 data bus and one did not work. Found out that he had three terminating resistors on the thermostats RS485 data bus. That was placing too much load on the data bus and the second thermostat would not work.
