Where granular temperature readings are available to control scripts, it
would also be possible to implement something like the tiers described
below. Adjust thresholds as deemed appropriate for the facility and
equipment, and also for the expected rates of temperature rise. System

Most EPO “mushroom” buttons can be wired either NO or NC.

I was assuming the EPO trigger is a circuit that is normally OPEN
and is closed when the button is pushed.
If instead, it is a normally-CLOSED circuit, then you are correct,
you would want two thermostats that both OPENED when the temperature
rose, which would typically be HEATING thermostats, not

We considered this approach, but we wanted to have notifications precede shut
down, and give a remote support person the ability to prevent the shut down.
Our SNMP based system gives us that option.

We use Intermapper, an SNMP network monitoring system, which supports UNIX
scripting. Intermapper probes two Weathergoose temperature sensors, and calls a
script with the values it retrieves. When both sensors exceed a certain
threshold, the script sends an snmp relay trip signal to the Weatherg

For safety, wire two thermostats in series so BOTH have to trip
before power is shut off.
Note that the EPO rarely does an orderly shutdown, but then this
is a sort of an emergency.
