Taco has added a new Multi-Volt Zone Sentry zone valve for use in hydronic heating and other HVAC systems such as those with fan coils and air handlers. The new mechanical valve allows one actuator to accept input voltages between 120 and 277VAC 50/60HZ.
Taco’s newest Zone Sentry Zone Valve – with an inverted flare – is suited for retrofit and new construction work. According to the company, the zone valves improve the overall performance of any hydronic system that uses a zone valve. Taco’s zone valve line uses microcircuit-based logic to control a gear-driven electronic actuator that drives a ball valve-based body design.
The new JS Series BACnet thermostat from Jackson Systems combines the power of a space-mounted equipment controller with built-in temperature and humidity. The thermostats include a wide range of factory supplied programs for the following applications: two-pipe and four-pipe fan coil units, roof top units, heat pump units and packaged and split unitary systems.
Many engineers tend to avoid or delegate the nitty gritty of a ground source heat pump system, from soil moisture effects to building system (im) balance. It's time for designers to get in the loop.
