For modern, high-efficiency hydronic systems, the actuator is the final bridge between smart control and real-world comfort. While traditional wax element actuators have been the industry standard for decades, the Saswell SA905-T Stepper Motor Actuator is redefining the performance ceiling of Underfloor Heating (UFH).

The most common complaints regarding underfloor heating (UFH) systems are uneven heating (hot and cold spots) and excessive running costs. Often, the fault lies not with the boiler or the pipes, but with the system's "brain"—the method of control used by the actuator. Traditional UFH actuators simply cannot meet the demands of modern, high-efficiency heating systems.

HVAC systems are classified as either self-contained unit packages or as central systems. Unit package describes a single unit that converts a primary energy source (electricity or gas) and provides final heating and cooling to the space to be conditioned. Examples of self-contained unit packages are rooftop HVAC systems, air conditioning units for rooms, and air-to-air heat pumps.

Remember, this is for electric water heaters

The majority of modern heating/cooling/heat pump thermostats operate on low voltage (typically 24 volts AC) control circuits. The source of the 24 volt AC power is a control transformer installed as part of the heating/cooling equipment. The advantage of the low voltage control system is the ability to operate multiple electro mechanical switching devices such as relays, contactors, and sequencers using inherently safe voltage and current levels. Built into the thermostat is a provision for enhanced temperature control using anticipation. A heat anticipator generates a small amount of additional heat to the sensing element while the heating appliance is operating. This opens the heating contacts slightly early to prevent the space temperature from greatly overshooting the thermostat setting. A mechanical heat anticipator is generally adjustable and should be set to the current flowing in the heating control circuit when the system is operating. A cooling anticipator generates a small amount of additional heat to the sensing element while the cooling appliance is not operating. This causes the contacts to energize the cooling equipment slightly early, preventing the space temperature from climbing excessively. Cooling anticipators are generally non-adjustable.
