Programmable room thermostats Overview Programmable room thermostats: The optimal solution for need-based temperature control MODERN DESIGN, NEED-BASED CONTROL feeling and famoso product lines Programmable room thermostats are mainly used for control of heating systems, underfloor heating, radiators or electric heaters. They can be easily integrated into any room through their simple and modern design. The digital programmable room thermostats of the feeling product family enable quick and suitable single room control. These chronostats have different operating modes which enable a comfortable indoor climate according to the individual needs. The large display ensures user-friendly programming and operation. The feeling D201 OT has an OpenTherm interface through which control of modulating heating systems is made possible. The analogue programmable room thermostats of the famoso product family feature an electronic temperature controller and analogue timing. Two temperature controllers, which can be selected via a selector switch, are used for setting the individual comfort temperature. The radio receivers for famoso and feeling room thermostats allow individual placement in the room without the laying of electrical cables. The simple surface mounting is particularly well suited for use in new buildings as well as in the replacement of existing installations. The programmable room thermostats from Grässlin are distinguished by their ease of handling and exemplary menu. 26

Digital universal & heating time switches QEG-1, QEG-1S, QEG-2, QEG-2S Digital universal & heating time switches QEG (Phase-out items) QEG-1, QEG-1S QEG-2, QEG-2S PRODUCT DESCRIPTION The QEG-1 and the QEG-1S are digital single-channel time switches and the QEG-2 and the QEG-2S are two-channel digital time switches for use with room thermostat with up to 3 different time periods, helping to control the entire central heating system in the house. The clock has a large, easy to read and back-lit LC display with real-time clock. The clock time is set at the factory and is maintained by a battery for many years. The time switch has an integrated automatic summer/winter change conforming with BST - GMT national time so that both the correct date of the time change and the time display are maintained. The programming is very easy through just three clicks using large, ergonomic buttons. In addition, the S variants feature a boiler service interval reminder for easy monitoring and early display of the maintenance date for the heating system. The QEGs are distinguished by a simple and modern design with a low profi le and easy installation. Convenient programming and reading of information by very large display SPDT - Single Pole Double Throw Up to 3 ON/OFF commands (selectable in pairs) per day provide a comfortable room climate Optimal tamper protection through PIN code protection for the service interval settings Boiler service interval reminder for easy monitoring and early display of the maintenance date for the heating system Convenient and simple reading of information through back-lit display, even in low-light conditions APPLICATION AREAS Boiler Combi boiler Domestic heating systems for heating and hot water preparation Pump controlled central heating systems Gravity heating systems CIRCUIT DIAGRAMS DIMENSIONAL DRAWINGS N L N L 1 2 3 4 Mains input OFF ON output timeswitch / programmer wallplate QEG-1 QEG-1S 148 148 95 36 95 36 N L 230 V / 50-60 Hz N L 1 2 3 4 HW OFF CH OFF CH ON HW ON timeswitch / programmer wallplate QEG-2 QEG-2S QEG-1, QEG-1S QEG-2, QEG-2S 56
