*Thermistor voltage signals varies according to temperature at
thermistor; see Thermistor Characteristic Tables 59 and 60 for
correlation of temperature and volts at these channels.
†When accessory transducer/sensor package has been installed
(requires changes in “Factory Configuration” inputs).
**Use relay HK35AB-001 (SPDT — pilot duty) for external control.
††Field-connection from building/energy management system.
||Field-connection to room terminal heating interlock.
