Temperature Controllers
AHU Temperature Controller
The standalone micro-controller based LCD temperature controller provides proportional plus integral (P+I) and on/off temperature control for commercial heating, ventilating & air conditioning system.
Overview
The standalone micro-controller based LCD temperature controller provides proportional plus integral (P+I) and on/off temperature control for commercial heating, ventilating & air conditioning system such as hydronic heating, air handling unit, heat exchanger or condensing tower. This controller has a modulating 2 to 10Vdc or 4 to 20mA analogue output and a 2A on/off output to realize various optional control functions including cool/heat changeover, heat/cool sequence control, emergency interlocking and auto-alarming control.
Features & Benefits:- PI control action provides accurate, stable and comfortable temperature control
- Backlit LCD to display both setting and measured value
- Adjustable Zero Energy Band, On/Off Differential, Proportional Band and Temperature Offset
- Optional 2 to 10Vdc or 4 to 20mA direct acting and reverse acting Analog output
- Selectable internal and external temperature sensor
- Wide temperature control range
- Watch Dog Timer to resume the controller from hanging condition
- Brownout effect to avoid malfunctioning and care on power On and power Off
- Pluggable terminal block allows pre-wiring outside of the controller
