Air temperature sensor must be installed across air temperature sensor contacts. The sensor is not activated and can be left stored in controller enclosure.

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.
