Hanging furnace and water pump

●If any of the temperature controllers in the eight areas have output, the hanging furnace will be started.
●After the hanging furnace starts,the delay is 120 seconds,and the pump starts to work.

·The hanging furnace is passive output,and theworking voltage of the pump is AC 220V. If the hanging furnace works normally,the matching temperaturecontrollerisnormallyclosed.

ProductFeatures

The direct supply center is suitable for small and medium-sized highand low temperature mixed heating and cooling systems. Itcooperateswith thehydraulic pressuredividertorealize the secondary circulationand control of the high temperature heatingor cooling system of the radiator in the secondary heating system. The direct supply center system includes a variable frequency circulation pump,a supply and return water temperature meter,and a secondarysystemballvalve.Itisalsoequippedwithaprefabricated hot-pressed insulation shell,which iseasy to install and use.This direct supply center is designed to be used with a hydraulic pressure divider with a spacing of 1 2 5mm to achieve independent operation of the first and second systems.

Product Features

·Ina radiantfloor heating/coolingsystem,the temperatureof thewater supply needs to be changed according to the heat load of the system and thechanges intheoutdoor temperature inorder to trulyachieve energy saving and comfort. Thecombination of the electric adjustable temperature control center andthetemperatureregulatorcanrealizethefixed-pointcompensation temperatureadjustment or theclimate compensationadjustment. The temperature control center includes an electric three-way mixing valve,abuilt-in temperaturesensor,avariable frequencycirculation pump,a supplyand return water temperature meter,andasecondary system ball valve.It isalso equipped withaprefabricated hotpressed insulation shell,which is very simple to install and debug. This temperature control center is designed to be used with hydraulic pressure dividers and manifoldswitha spacing of 1 2 5 \mathsf {mm } toachieve independent operation of the primaryand secondary systems.
