Components of control technology

ER interior thermostats
Three different models are available: “Control,” “Comfort,” or “Standard” The appealingly designed interior thermostats feature a dial for setting the room temperature in a range between 10 and 28 °C. The highquality thermostats have integrated pulsewidth modulation that equalises variations in
room temperature.
ER/C interior thermostat “Control”
The interior thermostat “Control” is equipped with a digital clock and can be used to program time controlled temperature settings of a room or as a pilot clock for several rooms (room group control). A variable temperature reduction of 2 to 6 °C is integrated.
ER/K interior thermostat “Comfort”
The interior thermostat “Comfort” is equipped with a variable temperature reduction mechanism of 2 to 6 °C. A selection switch can be set to ON, OFF, or AUTOMATIC; an LED indicates the selection. Automatic time control can be set through the interior thermostat “Control” acting as a pilot clock or through a digital clock at the control module.
ER/S interior thermostat “Standard”
The “Standard” interior thermostat is preset for a temperature reduction of 4 °C. Automatic time control can be set through the interior thermostat “Control” acting as a pilot clock or through a digital clock at the control module.
ER/KKH thermostat, for“Comfort cooling/heating”
The “Comfort cooling/heating” thermostat can be reversed by the control module extension ESME/KH and is therefore capable of regulating the room temperature for cooling/heating. The operating modes cooling (“Ice crystal” symbol) and temperature reduction (“Moon” symbol) are shown with separate LED indicators.
The unit is equipped with a variable temperature reduction setting from 2 to 6 ºC. The digital clock ESME/T can be installed in the control module for automatic timer control.

ESM control module
The Schlüter control module is the switch connection between the interior thermostats and the actuators. Up to six interior thermostats with 1-4 actuators each can be connected. The total number of connected actuators is limited to a maximum of 14 (13 for wireless operation). Control module expansions can be plugged in.

ESA actuators
The Schlüter actuators regulate the flow at the individual cold leg valves of the heating circuit distributor (each actuator controls one heating circuit). They are equipped with an optical function display and a valve adaptation control. They are easy to install by plugging in.

ESME/SA actuator expansion
With the ESME/SA expansion, more than four heating circuits monitored by actuators can control one or two large rooms. The expansion allows for 1 to 8 additional actuators for one room or 1 to 4 additional actuators for two rooms. The total number of connected actuators is limited to a maximum of 14 (13 for wireless operation).

ESME/R interior thermostat expansion
With the expansion ESME/R, two additional interior thermostats with 1 to 4 actuators each can be added to control more than six rooms. The total number of connected actuators is limited to a maximum of 14.

ESME/KH-expansion cooling/heating
The ESME/KH extension can switch all ER/KKH thermostats that are connected to the control module (24 V) from cooling to heating and vice versa. The switching takes place by way of a potential free contact on the side of the heat or cold generator or manually by pushing the set button on the control module extension. The operating modes (cooling, heating, or automatic mode) are shown by LED indicators.

ESME/P expansion of pump control
With the expansion ESME/P, the pump of the heating setup can be controlled energyefficiently by demand. The device also has a setting for delayed offset flow.

|
|
ESME/T timer/digital clock expansion
The ESME/T expansion is a digital clock for the time-control of two different heating zones with separate heat reduction phases. It is suitable for daily or weekly programming.
