Gas Heat Override
Note: See section Gas Heat Override Enable/Disable for enabling and disabling this feature.
Gas Heat Override operation is an algorithm for calling for additional stages of heat when the thermostat
determines more are needed. The two escalating stages are shown in Table 5. This logic is disabled when
both stages are not available.
Staging
Heat Source
Stage 1
Heat Pump/Heat Strip
Stage 2
Gas/Hydronic Heat
Table 5 - Heat Staging
Table 6 shows how Gas Heat Override affects the heat pump and heat strip operational modes when
enabled. This applies to heating cycle calls in auto operational modes as well.
