HEP 25MBH Isolation Heat Exchanger Panel Lite

The main application of the HEP Isolation Heat Exchanger Panel is to provide single wall isolation between a DHW tank and a heating system where a 24hr timer is not required. This panel is not a temperature control device; the secondary water temperature is dependent on the primary water temperature.

The panel is pre-wired to work with an optional DHW priority switch which is mounted outside the panel.

A cover for these panels is sold separately.

Sequence of operation:

• When a thermostat calls for heat, its internal 24V contacts close, the auxiliary terminals close, and both pumps turn on.
• When the requirements of the thermostat are met, the internal contacts of the thermostat open, the auxiliary contacts open, and the pumps stop.
• If the optional DHW priority flow switch is installed and the DHW flow is above the factory setting for this device, the primary pump stops and the auxiliary contacts open. When the DHW flow drops below the factory setting the panel resumes normal operation.
