To Interrogate
When E:EE is displayed switch unit off and press the temp up and temp down
buttons simultaneously for 3 seconds.
To Return to Normal Operation
Press Temp Up and Temp Down Buttons together for 3 seconds.
To Initiate Test Operation
Switch Unit Off & Press Master & Fan Buttons together for 3 seconds.
Press Start/Stop to Initiate.
Changing the Sensor Position
The unit can sense the air temperature at the unit or controller
Turn Unit Off
To change press THERMOSENSOR button for 5 seconds to unlock
Toggle the THERMOSENSOR button & controller is displayed
Set to desired setting (unit or controller)
Press THERMOSENSOR button for 5 seconds to lock
Two Handsets/1 Unit – set on RC DIP SWs
Single handset DIP SW1 is On & 2 is Off
Dual Handset Master Both On & Slave both Off
Group Control up to 16 Unit from 1 RC Handset
Set DIP SW3 on RC to ON
Set Each ID Unit Rotary SW to Unit Address (0-15) in series
Auto Restart on Power Failure
DIP SW2-3 on ID Unit. Off is autorestart (std)/On is Manual Restart
