2. Disconnect wires from J6-11 and J6-12. Measure
the voltage between J6-11 and J6-12, should be
about 32 VDC.
3. Reconnect wires to terminals J6-11 and J6-12.
Measure voltage again between J6-11 and J6-12,
voltage should flash high and low every 0.5
seconds. The voltage on the low end will measure
about 19 VDC, while the voltage on the high end
will measure from approximately 24 to 38 VDC.
4. Verify all modes of operation, by running the unit
through all of the steps in
5. After verifying proper unit operation, exit the test
mode. Turn the fan on continuously at the ZSM, by
pressing the button with the fan symbol. If the fan
comes on and runs continuously, the ZSM is good.
If you are not able to turn the fan on, the ZSM is
defective.
RLCI Loss of Communications
If the RLCI loses input from the building management
system, the RTRM will control in the default mode after
approximately 15 minutes. If the RTRM loses the
Heating and Cooling setpoint input, the RTRM will
control in the default mode instantaneously. The
temperature sensing thermistor in the Zone Sensor
Module is the only component required for the

Zone Temperature Sensor (ZTS)
Service Indicator
The ZSM SERVICE LED is a generic indicator that will
signal the closing of a Normally Open switch at any
time, providing the Indoor Motor (IDM) is operating.
This indicator is usually used to indicate an airside fan
failure.
The RTRM will ignore the closing of this Normally
Open switch for 2 (±1) minutes. This helps prevent
nuisance SERVICE LED indications.
