DIGI-SPAN® HWE-Elite & SEQ-3 Series
Residential Hot Water Outdoor Reset Boiler and Motorized Valve Heating Controls
Application

Simple affordable outdoor reset boiler and motorized valve controls for residential and small commercial applications. Now even smaller commercial properties and homeowners can enjoy the benefits of outdoor reset controls affordably and without complicated wiring or installation. Thanks to the new HWE-Elite and SEQ-3 Series. These controls can manage building temperature using outdoor reset, the most comfortable and efficient means of heat while providing fuel savings.

The HWE-SS is an outdoor reset boiler control with many built-in features.  In addition to its single stage boiler reset capability, it has domestic hot water priority options. It can be used to operate a domestic hot water pump and change the boiler water temperature to satisfy domestic hot water demand.

The HWE-MOV is an outdoor reset motorized valve heating control. Primarily used in radiant application where it will modulate a 3-way valve to achieve better control of building heat. It offers boiler return protection where it will reduce the water temperature giong to the heating zone if it senses that he boiler return temperture was low.  Thus, protecting the boiler from condensing and thermal shock.

The SEQ-3 is a multiple boiler outdoor reset control. It can operate up to 3 boilers or a 2-stage boiler (Lo/Hi).  It has built-in domestic hot water priority.

Note: The HWE Elite series replaces the Heatrol HWM series controls
