The thermostat allows for the furnace to cycle on and off during a defrost in order to temper the discharge air, and it protects the compressor from high refrigeration pressures during defrost. Installation installing the DT1 Discharge Thermostat Probe The DT 1 discharge thermostat probe must be installed between the indoor coil and the furnace, 1 - Find a location to install the probe that is on the the coil endplate. Ensure that the probe will clear all plumbing, 2 - Remove the endplate from coil and cut a hole approximately 2” in diameter to allow for the DT 1, 3 - With airflow arrow pointing in the appropriate posi- tion, use the four provided screws to secure the probe to the endplate, 4 - Replace the endplate to the coil, 5- Using field-provided thermostat wire, connect the DT1 (S89) to the W1 terminal of the defrost board and W1 terminal of the furnace. See figure 2, DT1 Discharge Temperature Probe Installation Location evaporator DT1 must be installed between the furnace and the evaporator coil with airflow arrow in correct position.
