RF upgrade sensor; ■ Fitter’s manual. Introduction This manual is intended for fitters who will install and perform maintenance on the CO

RF main control unit and/or the CO

RF upgrade sensor. This manual has been compiled with the great- est care. However, no rights can be derived from it. Zehnder - J.E. StorkAir also retains all rights to change the contents of this manual without pri- or notification. Warranty and liability Zehnder - J.E. StorkAir provides a 24 month war- ranty following installation and 30 months as of the production date. The warranty period com- mences on the date of purchase. The warranty becomes invalid if: ■ Installation has not been carried out ac- cording to the applicable regulations; ■ The defects are due to incorrect connec- tion, inexpert use, or contamination of the system; ■ Parts have been used which have not been supplied by the manufacturer or repairs have been carried out by unauthorized personnel. On-site (dis)assembly costs are not covered by the terms of the warranty. This also applies to normal wear and tear. Zehnder - J.E. StorkAir re- tains the right to change the construction and/or configuration of its products at any time without being obliged to alter previously delivered prod- ucts. Summary and principle The ventilation system comprises a ventilation unit with RF function and a CO

RF main control unit, which have a wireless connection. CO

upgrade sensors can be added. The main con- trol unit can be used to select between CO

-con- trolled ventilation or traditional 3-position switch control. The main control unit should be fitted in the living room. The upgrade sensors should be fitted in the bedrooms. The sensors are not in- tended for fitting on landings, hallways, toilets or bathrooms. The sensors and the ventilation system must be aligned before remote control of the system is possible. The procedure will be described in de- tail elsewhere in this manual. Electrical dangers There is a risk of electric shock during installation or maintenance. Always comply with safety regulations in this12 - EN manual. If the safety regulations, warnings, com- ments and instructions are not complied with, this can lead to personal injury or damage to the product. Disconnect the electrical group to which the main control unit or upgrade sensor is con- nected, before opening the cover of the de- vice. Electrostatic discharge (ESD) There is a risk that PCBs may be damaged by an electrostatic discharge if electrical components have to be exchanged. For this reason, always take ESD-inhibiting measures when dealing with PCBs, such as wearing an antistatic wristband. Do not use the CO

sensor for safety- related control of the gas supply, as it is intended only for use in living areas. The CO

sensor can be disrupted by other RF transmitters. Installation Installation The CO

RF main control unit and the CO

upgrade sensor are constructed from a sensor section (the front) and a transmitter section (the rear).

The transmitter section has been designed for mounting on a flush socket. The sensor section must be separated from the transmitter section in order to mount the devices on the wall and to electri- cally connect them. To do so, use a small screwdriver to press the 2 click fin- gers (B) in the air channels on the top of the device down- wards slightly and pull the sensor section up- wards. Note: When putting back the sensor section, the 4 pins (A) of the electrical connec- tion must fall into the contacts of the transmitter section. Ensure that the regulator is put back in a position that allows the air to move freely through the air channels. When selecting the position, en- sure that there are no large metal obstacles be- tween the ventilation unit and the CO

sensor. Di- rect radiant heat or warm supply air must also be avoided. The recommended position for the CO 2EN - 13 RF main control unit is next to the thermostat or light switch in the living room. The upgrade sen- sors should be fitted in the bedrooms. Electrical connections The CO

sensors must be connected in con- formance with locally prevailing procedures. The

sensor transmitter section is connected to the 230V/50Hz grid via a flush socket. Push the cables through the rear of the casing. Securely screw the transmitter section to the flush socket. Connection between the ventilation unit and the CO

sensors The following steps must be carried out to make a connection between the ventilation unit and the

sensors: Ventilation unit Ensure that the RF input of the ventilation unit is set to "proportional control". Consult the fit- ter's manual for the ventilation unit for more information.

1. Remove the ventilation unit plug from the

socket and replace after 5 seconds. The device is now in programming mode. A con- nection can be made with the main control unit within 10 minutes.

RF main control unit

RF main control unit for approximately 8 seconds. The sensor will now establish a connection with the ventilation unit. The green, orange and red LEDs flash to confirm that the com- munication has been established.

3. Repeat step 1. Use a pointed object (pa-

perclip or pen) to press the button on the upgrade sensor until the green, orange and red LEDs flash (approximately 8 seconds).

4. Repeat step 3 until all upgrade sensors are

connected. Connection problems The following problems may occur when con- necting the sensors or accessories: ■ The red LED on the CO

RF main control unit flashes. No connection has been established with the ventilation unit. Repeat step 1 and 2. If this is ineffective, check that the distance between the ventilation unit and the sensor is not too large and that the communication is not impeded by large metal obstacles; ■ The red LED on the CO

RF upgrade sensor flashes. No connection has been established between the CO

RF upgrade sensor and the ventilation unit, or the CO

RF main control unit is not connected. Check that the CO

RF main control unit is working properly. Then repeat step 3.14 - EN Operation Users can select one of 4 ventilation settings us- ing the button on the main control unit: absent, present, maximum or “Auto CO

”. The setting se- lected is indicated by a blue LED. The ventilation is automatically controlled in the “Auto CO

” set- ting based on the CO

concentration. When only the main control unit is used, this relates exclu- sively to the CO

levels in the living room. If the upgrade sensors are also used, then this highest

concentration is normative for the ventilation volume. The upgrade sensor does not function as a control unit and is only intended to monitor CO

levels in a living area. There are 3 LED indica- tors on the sensors which display the CO

levels: ■ Green (<1200ppm); ■ Orange (1200 – 1500ppm); ■ Red (>1500ppm). Residents are advised to open a door or window if the red LED lights up. Furthermore all gaps un- der doors - which are essential for effective ven- tilation - as well as the position of window grat- ings (if fitted) must be checked. Malfunction The following malfunctions can occur: ■ The green, orange and red LEDs flash. The 3-position switch on the main control unit still works. The CO

sensor is defective or seriously contaminated. Clean the CO

sen- sor or replace it; ■ The red LED flashes, while the green or orange LED is constantly illuminated. The sensor cannot establish a connection with the ventilation unit. Check the distance and for the presence of any large metal obsta- cles between sensor and ventilation unit. Maintenance The CO

sensors are maintenance-free through- out the entire lifespan. The operation can be in- terrupted by contamination of the air channels. Remove the dust from the casing and from the air channels where required. Specifications
