hP2 Displays the total hours auxiliary heat source has operated as

defined by relay R2 - Auxiliary pump ON time.

7.4.6 KWh and MWh Energy Monitoring

Display Only

These options are only shown when Energy Monitoring OHQM function is

set to ON and a sensor S4 is connected to the collector return pipework.

The heat quantity transported is determined from :-

1. The flow volume, as set by ‘FMAX’

2. The flow temperature of the collector, as detected by sensor S1.

3. The return temperature, as detected by sensor S4 (TRF).

The sum of both menu option KWh + MWh equals the total heat output.

Example MWh = 45 KWh = 750

45,000 + 750 = 45,750kW/h or 45.750MWh
