Electronic room temperature controller for proportional and three-point actuators
The constantly operating and three-point thermostatic room temperature controllers E 1 or E 3 respetively in conjunction with the corresponding actuators are employed in the field of heating, aerating and air condition engineering. Especially in those cases where elevated requirements for an accurate temperature control or a controlled system of high degrees of difficulty pevail opitmal control results can be achieved.
Technical description
The HEIMEIER Thermostats E 1 and E 3 are micro-processor-operated electronic room temperature controllers with incorporated sensors and adjustab PI control behaviour.
The Thermostat E 1 with constant control behaviour (0 – 10 V) allows connecting proportionally operating motorized actuators, e.g. EMO 1 or EMO TM.
The Thermostat E 3 with a three-point output signal will be used in conjunction with three-point motorized actuators such as e.g. EMO 3 or in case of a puls-width modulated output signal (PWM) with two-point actuators, e.g. EMO T or EMOtec.
The setting value is adjustable between 10° and 30°C. An upper or lower limitation of the setting value range can be effected by arranged hidden stops.
A"presence" push-button allows during heating mode, e.g. a room temperature set back by 4 K. Control lights indicate the operating mode such as "presence" and heating or cooling.
Two inputs for potential-free normally open (n/o) contacts allow connecting, for the temperature set back (X1), an external timing clock or for the purpose of a change-over from heating to cooling mode (c/o) an external switch respectively. There are further connecting possibilities for an external temperature sensor (Text), dew point detector (TP) and for a setting value shift (w).
The thermostatic controllers E 1 and E 3 are designed for an installation on a wall or on a recessed (concealed) socket.
