DIN rail heating controller EK-HH1-TP

for heating and coolingfor underfloor heatingfor valves

Description
The Ekinex® EK-HH1-TP mixing actuator/controller enables control of a hydronic mixing group by driving a mixing valve servo (3-point floating or 0–10 V), controlling a pump/circulator and acquiring supply and return fluid temperatures plus external air temperature. Supply temperature can be regulated in fixed setpoint mode, with external climate compensation, or with external compensation and internal-condition recalibration. Regulation modes are selectable separately for heating and cooling. The device is particularly suited to underfloor and ceiling radiant heating/cooling applications in combination with Ekinex® room thermostats with integrated temperature and humidity sensors. The membrane keypad allows manual control and includes status LEDs; the LCD displays and configures main operating parameters. The unit incorporates an integrated KNX bus communication module and is designed for 35 mm DIN-rail mounting. Bus KNX provides electronic power; mains 230 Vac is additionally required for actuator outputs.
