Single-zone snow melt control accessories

Two-wire, slow-opening thermal actuators mount directly onto EP heating manifolds to provide individual-loop flow control on a multi-zoned manifold (a manifold serving more than one zone). Note: See actuator-to-manifold compatibility table on page 96.

SetPoint 521 programmable thermostats are designed to sense air, floor or both temperatures with the ability to select one or the other as the primary sensing point. The thermostats also include multistage functionality along with programmable schedules.

Wireless base unit expansion modules easily connect to wireless base units to add an additional six thermostats and six actuators (for a total of 12 thermostats and 14 actuators in the system).Tip: The antenna will need to be disconnected and reinstalled on the expansion module when expanding the number of zones.Note: Not compatible with previous A360 Climate Control Zoning System products.

Single-zone pump relays control the operation of a single circulator or pump from a 24-volt signal. Relay includes secondary low-voltage terminals for boiler operation.Three-zone multi-pump relays control the operation of up to three pumps or circulators from dedicated 24-volt signals. Relay includes secondary low-voltage terminals for boiler operation and DHW priority options.
