11 Users Instructions
The Heat Bank Thermal Store Unit should be set up by the installer according to the instructions given in the Installation and Commissioning Instructions.
The unit is fitted with a Mixcall III Thermostatic Blending Valve, to control the hot water temperature, and prevent scalding.
Control Knob Position Min 1 2 3 4 5 6 7 Max
Outlet Temp. (°C) 27 32 38 44 49 53 58 63 67
Please not that under certain circumstances, increasing the flow rate of water from a tap or shower may result in the water temperature dropping. Likewise, reducing the flow rate will result in the temperature increasing - the temperature will not increase above the setting of the Thermostatic Blending Valve.
The Horstmann Electronic 7 Immersion Heater Controller controls the times when water is heated.  When set to timed, the unit will heat up on overnight electricity.  To heat the cylinder up at other times, a boost facility is provided.

For copies of Instructions, please telephone Horstmann on 01225 421141.
