Question from customer:
I want to use one device to turn on a hot-water circulator in my home for 15 minutes & then have it automatically turn off. I live in a 2 story wood home & the hot-water circulator is in the basement - maybe a distance of about 30 ft away through drywall & wood flooring. Will it work over this distance? Would I need to order a telescopic antenna?
Answer:
We think this product may be suitable for you– 1 channel ac delayed remote unit (0020483 S1DA-AC220-ANT2+CB-2). This kind of remote unit is with time delay timer, which you can adjust time according to your requirement. With external extend magnetic antenna, working distance of transmitter and receiver will reach 2000m/6000ft (theoretically).So you don't have to order telescopic antenna.
Wiring program is as follow:
We connect delayed remote unit to circulator pump. The receiver is relay output (normally open and normally closed). Power supply for the receiver and the water pump are different. That means it will not cause electromagnetic interference during water pump operation.
