tekmar Control Systems announced the addition of four new switching relay and zone valve control models to their existing line of zone control solutions.

tekmar now offers 2-zone pumps, 3-zone pumps, 3-zone valves and 5-zone valves. The newly added switching relays and zone valve controls are compatible with all low-voltage thermostats and offer a variety of benefits for homeowners, the company says. These include unlimited expansion; exercising, which prevents pumps from seizing during the summer; zone priority; and priority override to protect homes from freezing over the winter months.

The switching relays and zone valve controls also send out a RoomResponse signal to automatically adjust boiler temperatures to improve comfort, conserve energy and save money, the company adds.
