OK Master66, I haven't been thrilled with the control scheme as described. Please use a Fluke or equiv. with min/max record on AC amps , then AC mA. to make and break the circuit in place of the reed switch. Also check it on fast min/max record if you have that setting. Then also please tell us the actual measured value of your 24VAC control voltage. Also, if you can secure things, leave your Fluke on ACV min/max record across the 24VAC and walk away from it for a while. Check for higher voltage excursions. We can use the data gathered to determine if a current limiting resistor might be appropriate to protect the reed yet still provide enough to the coils.
