Hi, Can ISM007 switch boilers, two port valves or pumps on directly? Do the relay provide enough to switch these on. If not how can these used? I am not an electrician just need to understand. |

The relays are rated at 6 amps, so please look at the current rating of the valves to see if the ISM can be used to switch them directly. I expect it should be OK but please confirm |

Honeywell and drayton both draw ubder 3 amps to switch, so you should be fine. If your not an electrician do you know how to wire the valve ? Blue and brown energise the motor to switch, grey and orange are the normally open contacts. If you arent using the relay to power something else (such as a pump) You could use the contacts connected only to the ism07 input to confirm if the valve is open or closed. Hope that helps. |
