Hydronic Radiant Floor Heating: Zone Controls (Switching Relays)

The SP-81 universal single zone hydronic radiant floor heating switching relay is operated by low voltage thermostats or any other low voltage controllers having a SPST switching action. The SP-81 provides intermediate switching to permit up to two separate line voltage loads such as circulators.

The i-Link series 3-zone hydronic radiant floor heating switching relay for pump /circulator control is operated by low voltage thermostats or any other low voltage controllers having an SPST switching action. The i-Link controller provides intermediate switching to permit up to 3 circulators and a boiler operating control in a multi-zone hydronic heating system. Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with timer prevents freeze-ups in the event of a priority zone failure. Unique power surge protection to avoid damage to the unit and ensure continuous control operation.The panel provides EZ screwless terminal blocks for connections to the thermostats. LED indicators on the front panel provides functional status and easy troubleshooting. In addition, a system circulator is turned on whenever any zone calls for heat.

The i-Link series 4-zone hydronic radiant floor heating switching relay for pump / circulator control is operated by low voltage thermostats or any other low voltage controllers having an SPST switching action. The i-Link controller provides intermediate switching to permit up to 4 circulators and a boiler operating control in a multi-zone hydronic heating system. Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with timer prevents freeze-ups in the event of a priority zone failure. Unique power surge protection to avoid damage to the unit and ensure continuous control operation. The panel provides EZ screwless terminal blocks for connections to the thermostats. LED indicators on the front panel provides functional status and easy troubleshooting. In addition, a system circulator is turned on whenever any zone calls for heat.

The i-Link series 5-zone hydronic radiant floor heating switching relay for pump / circulator control is operated by low voltage thermostats or any other low voltage controllers having an SPST switching action. The i-Link controller provides intermediate switching to permit up to 5 circulators and a boiler operating control in a multi-zone hydronic heating system. Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers. Field selectable priority with timer prevents freeze-ups in the event of a priority zone failure. Unique power surge protection to avoid damage to the unit and ensure continuous control operation. The panel provides EZ screwless terminal blocks for connections to the thermostats. LED indicators on the front panel provides functional status and easy troubleshooting. In addition, a system circulator is turned on whenever any zone calls for heat.

The i-Link series 6-zone hydronic radiant floor heating switching relay for pump / circulator control is operated by low voltage thermostats or any other low voltage controllers having an SPST switching action.The i-Link controller provides intermediate switching to permit up to 6 circulators and a boiler operating control in a multi-zone hydronic heating system. Intelligent Linking System (i-Link) allows unlimited zone expansion with additional i-Link controllers.
