I'm assuming that the ?22mm pipe coming in from the left, the middle one of the three, is the feed from the boiler, which is then split two ways, down through the grey Honeywell to the DHW tank, which opens when the tank thermostat calls for heat, and horizontally through the white Danfoss to the CH system, which opens when the house thermostat calls for heat. Obviously my manual intervention cleared whatever gunk was preventing automatic actuation! This solution is, however, not recommended as you will not be able to know how much faster the actuator is actually moving.We recommend that you choose Danfoss AME actuators with BLDC motors technology as they have speed selection possibility on DIP switch.
