ANY COMBINATION OF RELAYS (U1, U2, U3) CAN BE USED. THEY ARE SET IN THE THERMOSTAT INSTALLER SETUP.

WIRE THE U RELAY TO THE LOW SPEED FAN FOR DEHUMIDIFICATION CONTROL AT THE EQUIPMENT. THE EIM RELAY CAN BE SET TO BE NORMALLY- OPEN OR NORMALLY-CLOSED IN

THE THERMOSTAT INSTALLER SETUP.

AN OPTIONAL 50027910-001 AIR-FLOW SWITCH (AFS) OR IS RECOMMENDED TO ENSURE AIR FLOW WHEN THE HUMIDIFIER IS RUNNING. IF THE AFS IS USED, SET DIP SWITCH 1 TO

OFF (LEFT). THE T10+ CAN BE CONFIGURED TO ONLY RUN THE HUMIDIFIER WITH A CALL FOR HEAT OR FAN, SO THE AFS WOULD ONLY BE NEEDED TO ENSURE NO WATER FLOW

THROUGH THE HUMIDIFIER PAD IF THERE IS A FAN FAILURE. THE T10+ CAN ALTERNATELY BE CONFIGURED FOR A FAN FAILURE ALERT (ISU 6000, 6150 AND 6160).
