Description
General
This 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 analog 2 to 10Vdc or 4 to 20mA 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
- PI (proportional plus integral) control action provides accurate, stable and comfortable temperature control.
- Compatible with series 70 direct-coupled damper / valve actuator like ML7161, ML7174, ML7420 / ML7421series ML7425, ML7984 series, N20010, S10010, M7410E series, CN7505, CN7510 / CN72 series CN7220 & CN7234 also VC79 series etc. •Backlit LCD to display both setting and measured value.
- Adjustable Zero Energy Band, On/Off Differential, Proportional Band and Temperature Offset.
- Analog output can be forced manually to be convenient for installation & commissioning.
- 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 (-20 to 110 °C by using external temperature sensor) is suitable for extreme temperature control such as steam and ice water. •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.
- Compact size and slim design provide elegant and attractive modern style appearance.
