The alarm thermostat will monitor high and
low temperatures for both thermostats 1 and 2
based on the following denition:
1: High = weighted value (r15). Low = weighted
value (r15)
2: High = weighted value (r15). Low = S4
3: High = S4. Low = S3 and S4. (50% from each)
4: High = S4 or S5. (Higher value is used)
Low = S3 and S4 (50% from each)
