Notes
These inputs can be configured for timed override capability.
Supports *, ** for Trane Zone Sensors.
Typically used for fan speed switch.
These inputs may be configured to be thermistor or resistive inputs,
0– 10 Vdc inputs, or 0–20 mA inputs.
Low impedance relay contact.
Minimum dwell time is 25 milliseconds ON and 25 milliseconds OFF.
The controller provides the 24Vac that is required to drive the binary
inputs when using the recommended connections.
Ranges given are per contact. Power needs to be wired to the binary
output. All outputs are isolated from each other and from ground or
power.
Note: Class 1 voltages shall not be used on Symbio 400–B/500
controllers.
Ranges given are per contact and power comes from the TRIAC
SUPPLY circuit. Use for modulating TRIACs. User determines
whether closing high side (providing voltage to the grounded load) or
low side (providing ground to the power load).
Each termination must be configured as either an analog output or
binary input.
Pressure inputs supplied with 5 volts (designed for Kavlico™
pressure transducers).
