Complete the connection, as per the following steps:
CONNECTING TO FCU/HVAC UNIT
Connect the cool (Y), heat (W), and fan
speed wires (Low, Med, Heat) to their
respective terminals on the module.
Connect the supply wire (24V,110V, or
220V) to module COM connection. All
inputs must have an appropriate voltage
source and an MCB to protect that load
circuit.

TROUBLESHOOTING
PRG Button Blinks Red Color
Rapidly
Reason: The Module address conicts with other
device in TIS network, you need to press and hold the
PRG button for 6 seconds so the module can get new
address
Device PRG LED is not Blinking;
Device not Powered
Reason: Device is not powered on; no TIS-BUS 24V
supply connected to the device.
Device Button LED is ON but
unit is not responding
Reason 1: Compressor / heat protection time enabled
Reason 2: Unit main supply is off.
Wall Panels can’t Pair with the
Device
Reason 1: TIS-BUS connection has a problem; check
the wires and make sure there’s not a short in the
connection.
Reason 2: Manual programming function disabled in
the device (default is enabled).
Wall Panels can’t Control the
Device Channels
Reason 1: TIS-BUS connection has a problem; check
the wires and make sure there’s not a short in the
connection.
Reason 2: Programming address is wrong.
HVAC Turned ON even when
the Wall Thermostat is Off.
Reason 1: HVAC stand-alone Logic enabled in
software.
