when stove is hot).
1 Select Geothermal Radiant Heat at ISU 201. Connect Fan to U1, U2, or U3 as shown in the wiring diagram.
2 "U" terminals are normally open dry contacts when set up for geothermal radiant heat.
3 L/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.

from the fan coil. If the wood stove is cold, only the fan runs. The thermostat will upstage to the heat pump and
backup heat as needed to maintain the temperature.
