HS115Plus Gas Boiler w/ HSPS120MTL Master Panel and Zoning Panel

Zone by Actuator

With Manifold, Tubing-in-Concrete Emitter, Actuator and Thermostat.


The Master Actuator Panel is utilized when 2 to 4 thermostat zones are required in the system. The panel extracts the heated fluid from the boiler and processes the heated fluid to the Emitter Circuit. Boiler and Emitter circuits have hydraulic separation for independent flow adjustments.

This system is used with a low temperature boiler and tubing-in-concrete emitter.

No zoning panels needed as the zones are controlled by the actuators located on the manifolds.
