  1. Caleffi Series 676 Two-way Thermoelectric Zone Valve Including Actuator

    Caleffi Series 676 Two-way Thermoelectric Zone Valve Including Actuator

    Caleffi Series 676 Two-way Thermoelectric Zone Valve
    Zone valves are used to control hot and chilled water in heating and air conditioning systems. Coupled with an electro-thermal control actuator and managed by a room thermostat, they allow automatic on/off control of the hydronic circuit on which they are installed. Their special feature is their compact size and they can therefore be installed almost anywhere including baseboard or directly in fan-coil units.

  3. Tjernlund Gas Pressure Switch

    Tjernlund Gas Pressure Switch

    Gas Pressure Switch
    The gas pressure switch is mounted on the casing of the water heater adjacent to the heater's thermostat/gas control valve. It should be mounted close enough so that the supplied 1/4" tubing will reach from the gas pressure switch fitting to the thermostat/gas valve pressure tap port. The two provided screws are self-tapping and drilling. The screws do not require the use of a drill and their 1/2" length assures that the inner tank will not be penetrated

  10. Johnson Controls Hot Water Cutout Temperature Control

    Johnson Controls Hot Water Cutout Temperature Control

    Johnson Controls Hot Water Cutout Temperature Control w/ Manual Reset (100-240F)
    Johnson Controls A19 Series temperature controls are designed to cover a broad range of uses for heating and general purpose requirements. Controls have SPST contacts which open on temperature increase or they may be supplied in single-pole, double-throw contact action. Various control ranges are available to cover working temperatures from -30 to 550° F (-34 to 288° C). Closed tank fittings and bulb wells are available for immersion applications. These controls are designed for open low and open high applications. Where critical or high value products are to be maintained within a specific temperature differential, a single control should not be applied to function as both an open low and open high control. In these applications, a separate backup control with alarm contacts should be wired to indicate when the back-up control operates.
