DOMESTIC HOT WATER APPLICATION SETUP PROCEDURE
1. Install a 10,000 Ohm, 1/8 Watt resistor between pins 1 and 2 on P2 connector (see pg. 13), in place of
the Outdoor Air Temperature Sensor. The Outdoor Air Temperature will appear to be about 77°F.
2. Set switch #2 (Outdoor Reset) to ON - 70°F Defeat, on S3. (See pg.s 15 and 23-24.)
3. Set the Outdoor Cutoff Temperature to 200°F. (See pg. 21.)
4. Adjust the Set Point to desired domestic hot water temperature. Controller will track the Set Point
Temperature. (See pg. 22.)
NOTE: The Outdoor Air Temperature sensor can be used as a replacement for the Water Temperature Sensor. Both
sensors are identical.
