Temperature Probes:
NTC
The control is shipped with an NTC (Negative Temperature
Coefficient) sensor, with a cable length of 7½ feet. Cable
length can be extended up to 400 feet by appropriately splic-
ing and adding additional cable (22 AWG or larger diameter)
PTC
The control may be connected to an existing PTC (Positive
Temperature Coefficient) sensor. Make sure the PTC sensor
meets the specifications tables below. Failure to do so will
result in temperature inaccuracies. The PTC input may not be

length, verify temperature accuracy and use the menu Ambi-
ent Temperature Offset (OFS) settings to compensate accord-
ingly if required.
extended more than 50 feet, and the wire gauge should be
18 AWG wire or larger diameter. Be sure the probe attached
matches the resistance vs. temperature tables or temperature
inaccuracies may occur.
