Fig. 321. Geothermal radiant heat with geothermal forced air and backup heat using separate transformer for the radiant 

heat.

1U1, U2 or U3 terminals must be used for geothermal radiant heat (ISU 201). Thermostat allows 2 stages of radiant heat—geo-

thermal (stage 1) and boiler (stage 2).

2“U” terminals are normally open dry contacts when set up for geothermal radiant heat. You must install a field jumper if radiant 

heat is powered by system transformer. Do NOT install a field jumper if radiant heat has its own transformer.

3L/A terminal sends continuous output when thermostat is set to EM HEAT mode except when set up for Economizer or TOD. See 

“Economizer Module Wiring Diagrams” beginning on page 132.

4Y2 used with heat pumps that have 2 compressor stages.

NOTE: For setup and operation, see “Geothermal Radiant Heat” beginning on page 78.
