or cool stage to on (1) or off (0). When HeatCoolMode is 0, then cooling loads are

controlled. When HeatCoolMode is 1 and the node is controlling conventional

equipment, then heating loads are controlled. When HeatCoolMode is 1 and the

node is controlling a heat pump, then cooling loads are controlled.

outputs are turned on or off manually. When HeatCoolMode is 0, then cooling loads

are controlled. When HeatCoolMode is 1 and the node is controlling conventional

equipment, then heating loads are controlled. When HeatCoolMode is 1 and the

node is controlling a heat pump, then cooling loads are controlled by Heat / Cool

stages and heating stages are controlled by auxiliary heat stages. The

CHANGE_OVER_RELAY_OUT is affected by HeatCoolMode as configured in

Select.
