TECH EU-391 zPID Chimney Controller with Throttle Valve & Touchscreen

Product description

The TECH temperature controller EU-391 zPID is a Fireplace control unit for water-bearing fireplaces/heating stoves. On the zPID algorithm Does the device automatically regulate the Combustion via a throttle valve and controls simultaneously ZH pump, Additional pump (hot water or underfloor heating), Buffer pump as well as a potential-free output for controlling external devices. Operation is convenient via Color LCD touchscreen – ideal for private customers with a heating fireplace and for installers in efficient system construction.

Highlights

zPID regulation for automatic combustion optimization (throttle valve)

Control of multiple pumps: ZH, Additional (WW/Floor), Buffer pump

Potential-free contact for controlling external devices/signals

Touchscreen + manual operating mode for service/commissioning

Optionally expandable with GSM module EU-65 and Internet module EU-505

Areas of application

Suitable for

Water-bearing wood-burning stoves/fireplaces for Combustion control via throttle valve

facilities with Heating circuit + hot water or Heating circuit + underfloor heating

Systems with Buffer storage (upper/lower buffer sensor)

Not suitable for

Applications without suitable Throttle valve/air duct by the fireplace

Installation by laypersons (assembly/connection by qualified personnel only recommended)

Technical data

Operating temperature: 5 °C to 50 °C (installation in the technical/boiler room)

Maximum pump output: 0.5 A (observe the permissible electrical load per pump output)

Potential-free contact (rated load): 230 V AC/0.5 A (AC1) or 24 V DC/0.5 A (DC1)

Sensors: KTY sensors −30 °C to 99 °C; Exhaust gas sensor -30 °C to 480 °C (combustion control/monitoring)

Backup: 2× 3.15 A (device protection)

Equipment: Color LCD touchscreen, exhaust/auxiliary/hot water sensor, throttle valve, upper & lower buffer sensor

Scope of delivery

control unit EU-391 zPID with color touchscreen

throttle

Sensors: Exhaust gas, central heating, hot water and upper/lower buffer sensor (depending on the version)

Conclusion

The EU-391 zPID fireplace control is a well-thought-out solution to Combustion, pumping and buffer charging to centrally control a water-bearing fireplace system. For operators, this means more stable temperatures and convenient operation, for skilled tradespeople clean system integration including potential-free output and optional remote monitoring.
