HRS-EAB
EDWIN
5-47W
1.8-3.7m3/h
4-7m
Application
The high efficiency intelligent circulation pump HRS-EAB series is designed for heating system, supply water in circulating of cooling air-condition, boiler and solar energy, to supply hot water and keep warm.
The pump is 100% copper, uses PES impeller, Ceramic bearing, Ceramic shaft, the shielding and cover is made of AISI304, the pump is with built-in thermal protector, it can be supplied with brass or iron connector, male tab connection or with different cable length and plug, if customer want different voltage and frequency, it is also ok. The warranty that EDWIN PUMP supplied is 1 year.
Function
The pump has totally 9 functions to choose.
PP1 means the duty point of the pump will only moves up or down based on the lowest proportional pressure curves, depending on the heating demand. If the heating demand is falling, the pressure also reduced; If the heating demand is rising, and the pressure also increased
PP2 means means the duty point of the pump will only moves up or down based on the highest proportional pressure curves, depending on the heating demand. If the heating demand is falling, the pressure also reduced; If the heating demand is rising, and the pressure also increased
CP1 means the lowest pressure curve is constant, and the duty point of the pump will move out or in, depending on the heating demand.
CP2 means the highest pressure curve is constant, and the duty point of the pump will move out or in, depending on the heating demand.
III means the pump runs at a constant speed which is also the max. speed. Rapid venting of the pump can be obtained by briefly setting the pump to speed lll.
II means the pump runs at a constant speed which is also the medium speed under all operating conditions
I means the pump runs at a constant speed which is also the min. speed under all operating conditions
AUTO is the ex-factory setting, so the pump power can automatically changed according to different flow of the system
Night mode can also be a choice. So the pump power can be automatically down after one hour, and down to 5-10W after two hours, then stop the auto mode and recovery to the original condition after seven hours.
