Does the SNOPRO-100 require a high-limit sensor?
SNOPRO-100 Series
The function of the high-limit sensor to monitor the slab temperature and protect the system against thermal runaway.
Therefore, “YES”, both versions of the SNOPRO-100 require the high-limit sensors to be wired to terminals 10 & 11 in the controller, either by the high-limit sensor that is included in both SNOPRO-100 or by putting in a 470k resistor as outlined on page 11 of our manual.
The high-limit sensor should be installed regardless of whether the SNOPRO-100 is used at a satellite or a stand-alone to protect against thermal runaway.
Page 11 from our manual states:
*If the high-limit sensor is NOT wired, the SNOPRO-100 will blink a green light and not activate.
