3. Make sure the power light is fast blinking If not then put DIP 3 to ON position 2 wire bus may be incorrectly connected Voltage at each Room sensor should not be lower than 4 0V check for amp continuity and short circuits For wireless Room sensors please check that the batteries have been inserted correctly For wireless systems has the init button been pressed For wireless Room sensor check that the WLRC2 19 receiver is correctly connected For channel 9 14 is the AO module correctly connected to the Master Make sure the Room sensor in that room is set to the correct channel number The channel selector on the Room sensor may be slightly out of position try rotating and the set it again Master has canceled install mode by itself after 2 hours the master automatically de activates install mode please reset the DIP 1 Make sure the Room sensor in that room is set to the correct channel number two Room sensors could be crossed over The actuator on the manifold has not opened after 3 minutes Check the red channel light is illuminated if not see above The actuator for the room is not connected to the correct output on the master Bad electrical connection between actuator and terminals Actuator may be faulty or manually locked UFH Pump not starting in install mode Bad electrical connection between pump and terminals Install mode is not activated Move dip switch 1 to the off position and
