By means of this principle of control hot CH water is available nearly all the time If in another room a closed radiator valve is opened the room will quickly be brought up to temperature as a result When to apply the room temperature controlled regulation When the house is heated only by means of radiators When not to apply the room temperature controlled regulation When there is no appropriate reference room in the house to install the IRT 30 When your house is heated also by means of floor heating air heating or convectors In practice the room temperature controlled regulation is the principle which will be selected in most cases Weather dependent regulation This is a principle of regulation in which the determination of the CH water temperature is achieved by the outside temperature and a number of preset values in the IRT 30 This can be necessary when no reference room is available Furthermore this principle is used in buildings where it must be possible to heat the rooms independently from each other for example old people s homes or office blocks For this principle the separate rooms should be equipped with radiators with thermostatic radiator valves in order to regulate the temperature in each room English 5 6 English In a house which is heated by floor heating the temperature fluctuations should not become too large Furthermore this kind of heating heats up and cools down very slowly

7. In this situation weather dependent regulation is a good choice because with this regulation the heating intensity of the boiler will only be affected by the outside temperature Because of this changes will take place relatively gradually What does the weather dependent regulation mean The heating intensity of the boiler is determined by the outside temperature and specific preset values on the IRT 30 clock thermostat When the outside temperature drops the boiler will burn more intensely and heat the CH water to a higher temperature up to a preset maximum temperature When the outside temperature rises the boiler will burn less intensely and heat the CH water to a lower temperature up to a preset minimum temperature The rooms will be heated by the continuously circulating CH water The temperature in the rooms to be heated can be regulated by means of thermostatic radiator valves When to apply weather dependent regulation When your house does not have a suitable reference room When you want to precisely regulate the temperature in more than one room When not to apply weather dependent regulation When your house does not comply with the above mentioned criteria This is a relatively less economical regulation principle so you should apply this kind of regulation only if strictly necessary Weather dependent regulation with room temperature compensation This kind of regulation is a derivative of the
