ZEM Merite - Evinox

Use of our diverter valve and hot water sensoractivates the dual modulation of the ZEMMerite boilers. With this activated the boilerwill fire at full power i.e. 17kW for the 2-17kWmodel and 25kW for the 5-25kW model toprovide priority hot water. After the hot waterproduction is finished then the boiler willmodulate between either 2-17kW or 5-25kWdepending on the heat requirement of theproperty based on the information from theroom unit and outside sensor.The selector valve and dual modulation hasbeen developed to provide the best and mosteconomical use of our condensing boilers. Useof our EBS hot water tanks will further enhancethe performance of the boiler due to the highoutput coil specifically designed to ensure thatall the boiler power is absorbed and the boilerremains in condensing mode during hot waterrecovery.External Selector Valve Kit for ConnectingZEM..C/BSThe external selector valve kit allows the connection of acentral heating only type boiler to a domestic hot watercylinder.Refer to kit installation instructions.ZEM-104-0Hydraulic connection for models ZEM C + DHW production system of type BS with externalselector valve kit1) Gas inlet2) Gas cock3) Boiler4) Radiator5) Heating flow isolation valve6) Heating flow7) Heating return isolation valve8) Heating return9) Cold water inlet10)Filling valve11)CB type disconnector12)Isolation valve13)Drain for condensates, valve, bleed14)Removal towards drain15)Outside sensor16)DHW production system of type BS17)Primary inlet18)Primary outlet19)Safety control box20)DHW expansion vessel21)Pressure reducer22)External motorized selector valve18ZEM-95-01521TKS16LMU17132019563M78122211D10211449
