There is an adjustment that can be made to the old "Gold"/Green" heads but TACO does not like you to do that.On the old heads with the thermostat calling go across terminals 1 and 2 you should read 24 volts. If not then problem is external (not the zone valve) If you have 24 volts the head should smell like it is burning, and it should get hot.Zone 1 and hot water work fine. Zone 2 is stuck in open position (Honeywell 8043f, lever has no resistance). Zone 2 only (and always) provides heat if hot water or zone 1 is requesting heat. However, if Zone 2's thermostat is requesting heat, the circulator and furnace do not come on. This is a one circulator system.Built-in Transformer and Relay.
