The max. number of HAI Tstats that may be connected to a single M1XSP is four (4). Max. wire distance = 500 ft. Each Tstat
must be assigned a unique address from 1 to 4. IMPORTANT: HAI Tstat addresses 1 to 4 MUST be connected to an
M1XSP that is set to data bus address 1. HAI Tstat addresses 5 to 8 MUST be connected to an M1XSP that is set to data
bus address 2. HAI Tstat addresses 9 to 12 MUST be connected to an M1XSP that is set to data bus address 3. HAI
Tstat addresses 13 to 16 MUST be connected to an M1XSP that is set to data bus address 4.

1. Install, and wire the HAI Thermostat to the HVAC system per the instructions that came with the thermostat.
2. Install the ELK-M1XSP as per instructions on page 3. Enroll the device into the M1 after setting the data bus address
switches. IMPORTANT: Refer to wiring diagram below and the note regarding which data bus addresses to use.
3. Set the MODE jumpers S5=1, S6=0, S7=1, & S8=0 for HAI mode. If the M1XSP has jumper S4, set it to =1. Set Jumper
JP3 to the "232" position. The BAUD jumpers S1,S2, & S3 do not matter as the HAI baud rate is preset internally.
4. Using a four wire cable and some splice connectors, connect the WO37A cable which is supplied with the ELK-M1XSP to
the Black, Red, Green, and Yellow wires of the four pin flying lead cable that is supplied with the HAI Thermostat. Plug the
WO37A cable into the 9 pin serial connector on the M1XSP, then plug the four pin cable into the HAI Thermostat.
5. Power up the HAI Thermostat, enter the Installer Setup Mode (see page 10 of the HAI manual), and program the following:
A. Set Item #00 "Address" to a value from 1 to 16. The first unit should be address 1. If multiple thermostats are
installed, each should be set to a consecutive address, starting at 1.
B. Set Item #01 "Communications Mode" to a value of 0 (300 baud, RS-232 mode).
C. Set Item #03 "Display Options" to one of the options designated as "non-programmable" (4 thru 7). This disables
the thermostat's internal setback time schedules so they do not override the M1 Automation commands from the M1XSP.
An alternate method is to disable specific schedules by setting their times values to "----" (1 step past the 11:45pm time set).
D. Set Items #05 & #06 "Cool Setpoint Limit" and "Heat Setpoint Limit" (if desired). CAUTION: The thermostat will
ignore any setpoint commands sent to it that are outside these limits.
6. Using the ELK-RP Software, program steps A,B, and C. Test and verify operation using steps D and E.
6a. Click on the Automation Tab in the ELK-RP software. Click on Thermostat icon and program a name for Thermostat 1.
6b. Click on the Task icon and program at least two tasks. Name the 1st Task "Economy Mode" and the 2nd "Comfort Mode".
6c. 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
6d. 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.
6e. 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 display.
