MOUNTING INSTRUCTIONS
Mounting of the Control Unit
It can be mounted in any dry room, e. Maximum permissible ambient temperature: 45 C.
Door Mounting
The casing cover is held by a snap hinge closure. [. . . ] Pull the controller insert out of the casing with the aid of the slide on the instructions case.
Press the left lock pin to the left with a screwdriver; by doing so, the case is freed from the device's base. Mount the device's base with two 0. 4 mm screws and dowels horizontally on the wall.
The assembly is to be carried out in the opposite order.
Electrical Connections
The electrical connections are to be carried out by a technician!

Cross sections
230 V AC 1. 5 mm (connection to the control unit, servomotor, pump) 18 V DC >= 0. 75 mm (connection to the sensors and selectors) The 18 V lines are to be laid separately from the 230 V lines. Use shielded cables in the presence of intense HF disturbance fields!
sing of this device model. floor heating) an additional thermostat is recommended to provide separate over-temperature limitation. With 230 V/50 Hz the servomotor and circulation pump require the jumper from terminal 5 to 6. The local regulations on earthing and resetting are to be followed carefully when connecting the device. Earlier temperature selector and sensor versions without additional letters A (e. TW 20, RF 20, TF 20, etc. ) have the same electrical connections and the same resistance values as the device versions with with additional letter A.

whether the control device is connected as illustrated in the wiring diagram.
Checking the Temperature Sensors and -Selectors
n The servomotor's sense of rotation can be deter-
mined by setting the control unit's operating mode selector on "auto" for ZG 252N or "auto" for ZG 215N / ZG 215VN and by changing the room target value on setting knob B (ZG 252N) or on the TW/TF (ZG 215N / ZG 215VN). LED Display Red Green Servomotor Opens Closes
By measuring the resistance it can be checked whether the temperature sensors and selectors are connected correctly. (The indicated terminal numbers refer to the markings on the sensors and selectors. )

If the sense of rotation is wrong, invert terminals 10 and 11 on the left-hand of the terminal strip.
Connecting the Potentiometer
If a potentiometer is used as feedback with the ZG 215N instead of the flow sensor VF 20, also terminals 4 and 5 on the right-hand are to be inverted besides terminals 10 / 11 if the sense of rotation of the actuator (mixer, ventilation valves), is wrong. When opening the actuator the resistance between terminals 3 / 4 of the motor must be lower, while the resistance between terminals 4 / 5 of the motor amounts always to 10 kW.
