Description: The company added Switching Relays 302P and 303P, as well as Zone Valve Control 303V and 305V, to its current line. The 302P connects up to two thermostats and operates circulators to provide heating to a zoned hydronic heating system. The 303P has the same operation but connects up to three thermostats. The 303V connects to three thermostats and operates a system pump whenever a zone valve opens. The 305V has the same functionality and connects up to five thermostats. The products are compatible with all low-voltage thermostats and offer 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.
