[mh] White Rodgers Type 1361 Zone Valves

[Cliff S. <cl...@ac...>]

Hi Folks - I'm looking for examples and circuit
diagrams about how to monitor these zone valves
in my heating system.

I'm going to stay away from weeder technology products.
Excellent products....but I already have a box that
will detect a contact closure/open and report it
via SNMP which is my preferred way of monitoring.
 From there I will graph it with MRTG/RRD to show
me when my zone vales are opening/closing.

My 3 thermostats are less than 3 years old.
Digital readout...temp/setback..all that.
But still...they're cheap units found in any
hardware store.

Wiring from thermostat to the zone valve:
3 wire...only wires are used. The contacts in
use are labeled W and RH. The thermostat seems
to source 24VAC to the zone vales when calling for heat.
I rue the day I did not specify cat5 for thermostat wiring
when they built this place.

I don't know much about zone valve/oil fired burner
lash-ups which is what I have.

Any ideas and/or circuit diagrams would be much appreciated.
I need a way of closing a relay. The relay contacts would
be hooked to the SNMP box. The SNMP box will not tolerate
AC or DC voltages being applied to the inputs. It will
sense a contact closure only.

Thanks All.
