To set the fl ow rate on the Freshwater Module on the Thermalstore 2.0, complete
the following steps;
• With the Thermalstore 2.0 hot, set the pump speed of the circulation pump (02)
to speed 3.
• Set the Thermostatic Mixing Valve (04) to its maximum setting by lifting the head
of the valve and turning.
• Set the Thermostatic Head Valve (01) to its lowest value.
• Close the Bypass Valve (03) fully and then open the valve by a quarter turn.
• Open a hot tap. Ensure that there is circulation through the Bypass Valve (03) as it
provides protection to the circulation pump in the event of the Thermostatic
Head Valve closing. If necessary adjust the Bypass Valve until you hear a trickle of
water pass through it.
• Set the Thermostatic Head Valve (01) to a desired maximum fl ow temperature on
the primary circuit. If a lower setpoint is chosen, there will be a greater volume of
available hot water.
• Take a temperature measurement at the kitchen tap by running the kitchen tap
half open.
• Adjust the delivered temperature at the tap by adjusting the setting on the
Thermostatic Mixing Valve (04) until the desired temperature is achieved.
