CAUTION
The thermostat’s digital outputs only control 24 Vac loads. The maximum rating is 1A
(24 VA) for each DO. Total maximum rating for the thermostat, including all energized
DOs is 4A (96 VA). Auxiliary Output 3 (OUT3) may be configured as a Dry Contact by
removing jumper RC-C3 and connecting the controlled device to both terminals OUT3
and C3.
An external interposing relay is required for any of the following:
- VA requirements higher than the maximum
- 110 or 220 Vac requirements
- DC power requirements
Configurable Inputs are Off (default). See RDY2000BN BACnet Enabled Commercial
Room Thermostat Installation Instructions 125-1009, 300 Series Parameters to
enable inputs. Temperature sensors that may be configured as Thermistor inputs are:
10K Type 2 (default) or 0 to 10V inputs. Humidity and CO2 sensors may be
configured as 0 to 10V inputs. Occupancy and Fault sensors may be configured as
digital inputs.
