The FlowCon T-JUST automatically controls the temperature of the water that cir- culates through the valve and therefore the thermal balance is ensured throughout the domestic hot water system. The T-JUST will from factory be pre-set to +60°C (+140°F). Temperature setting is easy - simply remove the black top cover and set the temperature by means of a FlowCon adjustment key. If for instance a water temperature of +55°C (+130°F) is needed, the T-JUST is set to the temperature of +55°C (+130°F). If the temperature of the circu- lating water is below +55°C (+130°F), T-JUST opens and more water will pass through. If the temperature is higher than +55°C (+130°F), T-JUST closes. The black top cap must be screwed tightly on the T-JUST to activate the thermostatic control (and to avoid tampering). The by-pass function can be carried out either manually by installing the red by-pass ring (used as indicator) or by means of an on/off actuator. The by-pass will force the T-JUST to fully open and set the temperature control out of action. This function is used to avoid bacterial problems such as Legionella and therefore it is recommended to flush the system regularly, flushing one branch at a time for a recommended period of time. For manual by-pass, adapt the red by-pass ring on the T-JUST and screw the black cap tight for the flushing period. When using automatic by- pass, the actuator can be either timer controlled or controlled by the BMS-system. For the valve to work efficiently, a certain heat loss must be present, and since the pipes are normally insulated, insulation of the valve is not necessary. Without insulation of the valve, the valve will operate under optimal working conditions and temperature regulation will be more accurate. If insulation is required the valve will still function, but regulation will be less precise.
