5.11.3 Thermostat to HVAC Equipment Wiring
The thermostat may not function properly if the total resistance
of any of th
e thermostat to HVAC equipment wires exceeds 2.5
ohms. To ensure that wire length does not cause excess
resistance, refer to Table 7 and ensure that the wires from the
thermostat to the HVAC equipment are not too long.

5.11.4 Remote Sensor to Programmable Thermostat
Because remote temperature sensors measure resistance, very
long cab
le runs can cause slight errors in the measurement. For
the highest temperature reading accuracy, avoid exceeding the
maximum recommended wire lengths show in Table 8.
