I have a System 2000 boiler with 1 pump and 2 zones controlled by zone valves. The zone valves open when the "brain" of the boiler places 24 volts on them.
One zone supplies hot water into a staple up radiant floor zone that predated the boiler install. This zone has its own pump already installed.
In the original configuration, the Radiant pump controller was triggered from a thermostat. The new boiler is much more sophisticated. and I want to use the built in "smarts".
The new configuration has thermostat input to one side of the boiler controller and outputs 24v on the other side when it decides to supply heat and open the valve
I was thinking of solving this with one of two ways:
1. get a new zone valve actuator with an end switch that would trigger the radiant pump when open.
2. get a new zone controller that triggers when 24v appears (as opposed to closing the switch). My zone controller does not perform this functions so it would need to be replaced. What could I use?
