power to energize the dehumidify terminal on the cooling equipment when the dry contact is closed.

If it is desired to operate a ventilator or other device, the D1 and D2 terminals can be connected directly to the equipment. This will provide a closed contact for the specified number of minutes per hour. See Option 19.

If timed control of the system blower is required, the dry contact can be used for this function. The G terminal can be connected to one of the dry contact terminals with the other terminal being connected to Rc and/or Rh for timed control of the fan. Note that this is not the same as programmable fan Option 30.

See Wiring Diagrams for more information.

TROUBLESHOOTING

If the display module doesn’t power up after power is applied, check the Rc/Rh and C terminals for 24VAC. If 24VAC is present, check the voltage between Vg and V+. This voltage will be approximately 12-20VDC. If voltage is present, check the polarity to make sure it is wired correctly. The display will not power up if polarity is reversed.

Error Codes

“--” - If Thermidistat Control cannot properly read room temperature, display will indicate “--” and all outputs (except fan, if on) will turn off. In the case where the installer has selected to average the local sensor and the remote room sensor, the Thermidistat Control display will alternate between “--” for the failed sensor and the temperature sensed by the working sensor every 10
