TMP 85MBH Dual Pump 3-Way Mixing panel

The TMP 3-Way Mixing Panel’s primary application is as a single temperature mixing device where there are no flow requirements in the primary loop.

Intended to be used with DHW tanks as a heat source, the PLC is programmed with a 24hr timer for
potable applications. The TMP085DP not only allows for higher output, but it is also a 2-zone panel. So
even with a DHW heat source, you can now have two radiant floor zones. When not used with a DHW tank as a heat source, secondary zoning downstream of the panel is possible.

A DHW priority option for this panel is not available.

These panels can also be used as subpanels

Sequence of operation:

• When the thermostat calls for heat, its internal 24V contacts close, the auxiliary terminals close, and the appropriate pump turns on.
• As the pump moves fluid through the panel the thermostatic mixing valve adjusts the fluid temperature based on the user settings.
• When the requirements of the thermostat are met, the internal contacts of the thermostat open, the auxiliary contacts open, and the corresponding pump(s) stops.
• The pump is activated once every 24 hours, for 15 minutes, to ensure that potable water in the piping is not stagnant.
