Definition of classes
Class I – On/off room thermostat: a room thermostat that controls the on/off op-
eration of a heater. Performance parameters, including switching differential and
room temperature control accuracy are determined by the thermostat's mechanical
construction.
Class V – Modulating room thermostat, for use with modulating heaters: an elec-
tronic room thermostat that varies the flow temperature of the water leaving the
heater dependent upon measured room temperature deviation from room thermo-
stat set point. Control is achieved by modulating the output of the heater.
Class VI – Weather compensator and room sensor, for use with modulating heaters:
a heater flow temperature control that varies the flow temperature of water leaving
the heater dependent upon prevailing outside temperature and selected weather
compensation curve. A room temperature sensor monitors room temperature and
adjusts the compensation curve parallel displacement to improve room comfort.
Control is achieved by modulating the output of the heater.
Class VIII – Multi-sensor room temperature control, for use with modulating heaters:
an electronic control, equipped with 3 or more room sensors, that varies the flow
temperature of the water leaving the heater dependent upon the aggregated meas-
ured room temperature deviation from room sensor set points. Control is achieved
by modulating the output of the heater.
