Technical description

Construction

1. Base plate
2. Operating device

Functional description
The surface-mounting room thermostat serves the individual temperature control. It is designed for fan coil units with two- and four-pipe systems.

Functional description surface-mounting room thermostat for two-pipe systems (item no. 1152064)
The surface-mounting room thermostat for two-pipe systems features:

• a 230 V fan drive (3 speeds)
• a 0-10 V control for heating or cooling
• a two point control for an additional heating
• two inputs (temperature sensor, key card)

(see also: “Illustr. 5: Connection diagram 1152064“) With the help of an external sensor, the surface-mounting room thermostat for two-pipe systems detects whether the system is in heating and cooling operation. This information is shown on the display. Switching between heating and cooling has to be carried out manually.

Functional description of surface-mounting room
thermostat for four-pipe systems (item no. 1152065) The surface-mounting room thermostat for four-pipe systems features:

• a 230 V fan drive (3 speeds)
• a 0-10 V control for heating
• a 0-10 V control for cooling
• a two-point control for additional heating
• two inputs (temperature sensor, key card)

(see also: “Illustr. 6: Connection diagram 1152065“) With the help of an internal sensor, the surface-mounting room thermostat for four-pipe systems compares the actual and the nominal temperature and automatically switches between heating and cooling. The current operating mode is shown on the display.

Technical data

Transport and storage
The product must be transported in the original packaging. The product must only be stored under the following conditions

Installation

General installation advice
The room thermostat should be installed at a location where a good circulation of air is guaranteed. If possible, the room thermostat should be mounted onto an inner wall at a height of 140 cm to 170 cm. Please make sure that the room thermostat is not affected by influenced by heat or cold sources (e.g. sunlight, cold outer walls). This is the only way to achieve a high measuring accuracy.

Wall attachment

• Loosen the two screws at the bottom of the room thermostat and remove the operating device from the base plate.
• Screw the base plate horizontally onto the wall. Use the drilling jig in the base plate for this purpose.
• Suspend the operating device into the base plate from thetop.
• Fix the base plate and the operating device with the help ofthe two screws removed under point

Commissioning
Cable the room thermostat according to the respective connectiondiagram (see “Illustr. 5: Connection diagram 1152064“ and “Illustr.

Configuration options

Menu option	Factory settings	Control range	Function
FC	°C	°C/°F	Select the required temperature unit.
CL	0	-4 up to +4	The room thermostat is calibrated when leaving the factory. If the room thermostat cannot be positioned in such a way that the room temperature is measured without being influenced by external disturbance factors, the deviations can be compensated by modifying the settings. The value measured at a cold outer wall would, for instance, be lower than the actual room temperature. In this case, the value can be corrected upwards. The displayed temperature can be increased/decreased by up to +/- 4 °C/F compared to the measured temperature.
CH	35°C	20°C to 35°C 68°F to 95°F	Select the maximum nominal value. During operation, this setting cannot be exceeded.
CC	5°C	5°C to 20°C 41°F to 68°F	Select the minimum nominal value. During operation, this setting cannot be undercut.
UC	18°C	10°C to 18°C 50°F to 64°F	Select the temperature for heating operation in night mode.
UH	25°C	25°C to 30°C 77°F to 86°F	Select the temperature for cooling operation in night mode.
PH	1	1-10	Select the height of the proportional band (P).
LP	5	0-10	Select the height of the integral part (I).
bL	1	1/2/3	Select between 3 types of lighting: •      1 = Lighting is switched on by pressing a switch •      2 = Permanent lighting •      3 = Lighting is permanently switched off
HF	h2	h1/h2/h3	Select between 3 control options: •      h1 = 0-10 V control for heating/cooling •      h2 = 0-10 V control for heating/cooling + two point control for an additional heating •      h3 = Two point control for an additional heating
En	AC	OU/AC	Select the used temperature sensor: •      OU = Return temperature sensor •      AC = Room temperature sensor
rC	SC	SC/OC/OO	Select the type of activation of the night mode via the key card function: •      SC = Night mode with a closed electrical circuit •      OC = <Night mode with an open electrical circuit •      OO = Night mode is terminated
OU	2	1/2	(only for item no. 1152065) •      1 = The room thermostat is working in the two-pipe system •      2 = The room thermostat is working in the four-pipe system
