The arrangement controls the circulating pump (5) and hot supply valve (7) using an auxiliary device (1) and the standard regulator (12) together so that the valve is closed in the summer mode. This is effected by converting the signal from the temperature sensor connected to the standard regulator using the auxiliary device. In normal mode the standard regulator regulates the hot supply based on one or more temperature sensors (3,12.1). The auxiliary device has its own temperature sensor (2) and control logic (24) for activating the summer mode depending on temperature. The auxiliary device has a moisture detector (30), elements (33,35) for forming moisture and temperature state signals, a time switch (37) and auxiliary logic which work together to activate the heating function when the specified temperature and humidity conditions are fulfilled over a set time period. |
