Embedded thermistor for measuring
Room Temperature
• When temperature is below 32°F / 0°C,
temperature keeps display LO
• When temperature is above 99°F / 40°C,
temperature keeps display HI
• Sensor open/short will show “
- -
“
• Heat and Cool output will be off when sensor
open/short
Remote water temperature sensor
(for 2-pipe systems only)
• When 2-pipe system is selected (2H or 2P
mode), remote water temperature sensor must
be present
• LCD flashes error code “E1” under the following
condition –
• Sensor not connected or shorted
• When “E1” is flashing on the display, all outputs
