Description
    The ES-759 is a special version of KEP's SUPERtrol II which offers a special feature that allows users to access Heating Total by pressing the TOTAL button, and Cooling Total by pressing the GRAND button when using Liquid Delta Heat Equation. The ES759 ST2 is intended for use as a heat flow computer for systems which are used for part of the year as a heating system and part of the year as a cooling system. There are separate energy totalizers for heat total and cooling total. This functionality assumes that Liquid Delta Heat Equation is selected. The energy units for the heating and cooling totalizers must be the same. The Low Delta T Cutout represents a "dead band" which the T2-T1 calculation must exceed before the energy flow rates (heat flow rate) will show as a numeric value other than 0, and where one of the energy totalizers will begin accumulating.
