IF IT IS A NEW THERMOSTAT AND ERM, SEE PAGE 14. IF IT IS AN EXISTING THERMOSTAT OR EIM SEE PAGE 16.
IF YOU FOLLOWED THE STEPS ON THOSE PAGES AND ARE STILL HAVING ISSUES, CONTINUE WITH THIS FLOW CHART.
VERIFY IT IS USED WITH COMPATIBLE EQUIPMENT. IF A THERMOSTAT AND EIM ARE USED,
BOTH HAVE TO BE COMPLATIBLE WITH THE ERM. SEE PAGE 3 FOR COMPATIBILITY.
WHEN THE THERMOSTAT IS AT THE SCREEN THAT SAYS "PRESS CONNECT ON NEW RedLINK
ACCESSORY" AND YOU PRESS/RELEASE THE BUTTON ON THE ERM, WHAT HAPPENS?
CONNECTION LED ON ERM FLASHES
GREEN BUT THEN TURNS SOLID RED.
THIS INDICATES THAT THERE WAS ANISSUE
WITH THE PAIRING. IS THAT THERMOSTAT
ALREADY PAIRED WITH TWO ERMS?
NO
YOU CANNOT PAIR A
THERMOSTAT WITH 3 ERMS.
TRY PRESSING/HOLDING THE BUTTON ON THE ERM TO RESET IT. THIS MAY TAKE 30 SECONDS OR SO. THE LED MAY GO OUT FOR A
FEW SECONDS, THEN COME BACK ON, THEN GO OUT AND STAY OUT. THIS RESETS THE ERM. AFTER THIS IS DONE, GET THE
THERMOSTAT BACK TO THE SCREEN THAT SAYS "PRESS CONNECT ON NEW ACCESSORIES" AND PRESS THE BUTTON ON ERM.
IF CONNECT LED ON ERM FLASHES GREEN AND GOES BACK TO SOLID RED, ONE OF THREE THINGS IS HAPPENING:
1. THE THERMOSTAT OR EIM IS NOT COMPATIBLE WITH ERM. SEE PAGE 3.
2. SOMETHING IS BLOCKING COMMUNICATION. IF THE THERMOSTAT USES AN EIM, THEN THE EIM IS THE HOST. IF YOU HAVE A
COMPATIBLE RedLINK 8000 SERIES THERMOSTAT AND DO NOT HAVE AN EIM, THE THERMOSTAT IS THE HOST. MAKE SURE THERE IS
NOTHING THAT IS BLOCKING THE SIGNAL BETWEEN ERM AND HOST. A METAL BOX, OR CONCRETE OR METAL CONSTUCTION
MATERIALS BETWEEN ERM AND HOST COULD IMPEDE THE SIGNAL.
3. THERE ARE ALREADY TOO MANY ERMS CONNECTED. SEE THE NOTES SECTION ON PAGE 3.
IF THE ISSUE IS NOT RESOLVED, PLEASE CALL THE SUPPORT LINE FROM THE SITE FOR FURTHER TROUBLESHOOTING AT 800-468-1502
BETWEEN 8-4:30 CST M-F.
UNABLE TO LINK ERM TO THERMOSTAT
CONNECTION LED
TURNS SOLID GREEN.
ERM HAS BEEN SUCCESSFULLY
LINKED TO THERMOSTAT.
YES
VERIFY CONNECTIONS TO R AND C AND
VERIFY 24 VAC TO THOSE TERMINALS.
SEE WIRING DIAGRAMS (FIGURES 10-15).
IF THE CONNECT LED DOES NOT FLASH WHEN YOU PRESS/RELEASE THE BUTTON,
THE ERM IS NOT RESPONDING. TRY PRESSING/RELEASING THE BUTTON AGAIN.
USUALLY YOU ONLY NEED TO PUSH IT IN FOR A SPLIT SECOND, BUT IF
UNRESPONSIVE, TRY HOLDING IT DOWN FOR A SECOND BEFORE RELEASING IT.
