HEVAC Endeavour Controller, microprocessor based Temperature/CO2 controller c/w 365 day time switch, 5 relays + 2 analog 0-10v O/P’s + MODBUS.

The HEVAC ENDEAVOUR controller is a programmable very flexible microprocessor based controller designed to control A/C & Fan Coil units via remote zone sensors with optional use of many internal & external features ie: 365 day Time Switch, Run Timer, Outside & Supply Air temperature sensors, CO2 sensor input, plus now with an assignable auxiliary universal control input (X4) for monitoring & control of a 2nd independent control loop, making this controller an ideal stand alone or BMS semi autonomous zone controller.

The ENDEAVOUR is mainly intended for applications where On/Off control of Heating and Cooling stages and / or modulating control of actuators, compressors or fans is required. The controller is suitable for mounting in a mechanical services switchboard or the A/C units control cubicle and connected to remote measuring sensors & optional override switches. Four of the five relays are programmable for their mode of operation as Compressor, Heating or Cooling stages, CO2, Auxiliary Time Switch, or controlled by external 0-10vdc input with individual editable switching characteristics. The 5th relay is dedicated as a System Run (fan / time switch) relay which can be set for cycle or continuous operation whilst the system is enabled. The two Analogue 0-10vDC output signals can be programmed individually for start, range, P or P + I mode of operation. The controller is lockable in 3 levels plus includes a basic data event logger. Other notable new features & enhancements include : I.O.T connectivity, A/C fault input, Automatic setpoint reset based on outside temperature & room humidity & can now be set to operate as a 4 channel 365 day Time Switch only .

Can be powered from 12-24vAC or DC, For systems to be powered from 240vAC see 240/24vdc low cost power supply.
