Honeywell - Modulating Thermostat
The T7984 family provides modulating analog 2 to 10 VDC
control
These microprocessor-based thermostats provide proportional –
integral (PI) individual room temperature control in zoned
commercial Heating, Ventilating, and Air Conditioning systems such
as Hydronic heating and/ or cooling, pressure dependent VAV or
by-pass box with or without terminal reheat.
Ideal replacement for T7072A/B.
-
Optional features include automatic heat/cool changeover, reheat control, remote night setback with local timed override, and remote sensor on VAV
