Swamp Cooler Wiring Diagram Cord Wiring Library Rh 40 Muehlwald De Swamp Cooler Thermostat Wiring Diagram - Fyi: the time postpone isn't essential, you can go away it out and the minute or so it takes your pads to get wet won't be worth it to you. I've coolers in my residence and do it each approaches and the time delay wasn't really worth the extra cost. However if most effectiveness is your desire then i'd positioned it in for the cost of pre-wetting the pads to save you warm air from coming into.

I have observed that the honeywell rc840t-a hundred and twenty might allow me to apply the 24v nest thermostat with the 110v swamp cooler and the usage of a spdt relay i should connect y1 and y2 to the 2 terminals of the two-pace motor. Honeywell rc840t-a hundred and twenty become created to attach line-voltage managed heaters to 24v thermostats but i suppose it's going to also work with the swamp cooler. This tool can be the first relay in order to determine if the pump and motor are going to receive energy. This primary relay could be linked to a ptd102 put off in an effort to postpone the electricity to the spdt relay, this closing realy is the one a good way to manipulate the power to the motor based totally on y2 terminal from nest thermostat. The thermostat will send strength to y1 best for 1st speed and in case it wishes extra cooling electricity it's going to start sending power to y1 and y2 on the identical time inflicting the spdt relay to exchange strength to excessive thru terminal 3 as the following diagram suggests:.

Before coping with the hassle to connect each structures to the identical thermostat (maybe using switches/relays to close down one machine at the same time as the opposite is on) i need to understand if it feasible to govern the swamp cooler the use of the nest thermostat. I do not have an excessive amount of electric understanding, however i have been doing a little research and that i think it's miles feasible if i buy some extra things.

I might positioned a pleasing 24v dpdt relay and a nice 24v 3pdt relay on the perfect mounting sockets and mount them to a din rail. This may make it clean and smooth. Put it all in a field with the transformer and the packard and voila.
