Using the RS-485 format, up to 16 RCS TR16/TR40 Thermostats total can be interfaced to an ELK-M1G (Gold) using 1
M1XSP. Each thermostat must have a unique address from 1 to 16. The ELK-M1 (Std) is limited to 2 thermostats total.
The brand of thermostat, interface format, and model of ELK-M1 Control dictates the total number of thermostats allowed.

(RS-485 format)
1. Install, and wire the RCS Control Unit and Wall Display Unit to the HVAC system per the RCS instructions.
2. Install the ELK-M1XSP per the instructions on page 3. Be sure to enroll the device into the M1.
3. Set the MODE jumpers S5=1, S6=0, S7=0, & S8=1 for RCS mode. If the M1XSP has jumper S4, set it to =1. Set Jumper
JP3 to the "485" position. The BAUD jumpers S1,S2, & S3 do not matter as the RCS baud rate is preset internally.
4. Using a 3 conductor cable and the diagram below, connect the GND, D+, and D- wires from the RS-485 terminals on the
RCS Thermostat Control unit to the RS-485 terminals on the M1XSP. The supplied WO37A cable (RS-232) is not used.
5. Power up the RCS Thermostat Control Unit.
6. Program the Unit Address and any other options in the RCS Unit per its instructions. The unit address must match the
Thermostat number in the M1 Control. The first Thermostat should be Address 1.
7. Using the ELK-RP Software, program the M1 using the following steps. Test and verify operation using steps d and e.
7a. Click on the Automation Tab in the ELK-RP software. Click on Thermostat icon and program a name for Thermostat 1.
7b. Click on the Task icon and program at least two tasks. Name the 1st Task "Economy Mode" and the 2nd "Comfort Mode".
7c. Click on the Rules icon and create the following 4 rules.
Whenever [Area Name] Armed State Becomes Armed Away Whenever [Task Name] (Task 1) Is Activated
Then Activate [Economy Mode] (Task 1) Then Set [Thermostat 1] (TStat 1) Cooling Desired Temp to 85 degrees
Whenever [Area] Armed State Becomes Disarmed Whenever [Task Name] (Task 2) Is Activated
Then Activate [Comfort Mode] (Task 2) Then Set [Thermostat 1] (TStat 1) Cooling Desired Temp to 70 degrees
7d. Use the M1 Keypad to verify the M1XSP & Thermostat operation. Press the ELK key followed by the Right arrow key to
access Menu 1-View/Control Automation Fncts. Press 6 for the Thermostat Temperature sub-menu, followed by Right
arrow key. The Keypad should display the first Thermostat (T01) along with its name and current temperature reading.
7e. Go into the Tasks sub-menu and select Economy Mode (Task 1). Press the # key to activate. When this task is activated
the thermostat cooling setpoint should go to 85 degrees. Confirm this on the thermostat display.
