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

• Network supply: 230 V ±10%/50 Hz (standard mains connection)
• Power consumption: 4 W (very low power consumption)
• 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.
