Zehnder ComfoControl Ease Installation Guide Overview

Summary of Contents

• Page 1: ComfoControl Ease Installer manual Heating Cooling Fresh Air Clean Air
• Page 2: This documentation has been compiled with the utmost care. The publisher cannot be held liable for any damage caused as a result of missing or incorrect information in this manual.
• Page 3: Installation conditions In order to determine whether the CC Ease can be installed in a certain area, the following aspects must be taken into account. Contact your supplier immediately in case of damage or an incomplete delivery. The CC Ease must be mounted at least 5 feet (1.5m) above the floor in a living area and be easily accessible for the user. The following facilities must be available in the living area concerned: documentation. Flush-fit casing for the CC Ease. 12V DC power supply from the ComfoAir. Take care when transporting and unpacking the CC Ease. The cable for connecting the CC Ease must comply with the following minimal requirements. Cable type: 2-conductor shielded twisted pair 4 x 22 AWG (4x0.34mm). Cable length: 131 feet (40m) maximum.
• Page 4: The system Wall mounting The CC Ease can be mounted in a standard wall-mounted or flush-fit casing. Wall-mounted casings in the same colour as the CC Ease are available from Zehnder. Cabling When connecting or disconnecting the CC Ease, the ComfoAir must first be fully disconnected from its power supply. This prevents current being supplied to the CC Ease unit’s input/output system. The CC Ease should always be crosslinked (Rx to Tx) with a 2-conductor shielded twisted pair 4 x 22 AWG (4x0.34mm) of up to 131 feet (40m). To ensure the CC Ease front section can be mounted correctly, the connector in the casing of the CC Ease must be located at the bottom. The ComfoAir installer manual indicates the connection point on the side of the ComfoAir.
• Page 5: Commissioning Use of the ComfoControl Ease The overview below summarizes the information that will be displayed on the CC Ease. Time and date Supply air or exhaust air ON or OFF Ventilation programme (AUTO) or manual ventilation (MANUAL) The CC Ease has a number of buttons to operate the ComfoAir and to enter the settings. This button switches to the highest ventilation setting. This button allows you to switch between supply/exhaust. This button allows you to display or set the comfort temperature. This button allows you to adjust two settings. While the open fire programme is activated the supply and exhaust fan cannot be manually switched off.
• Page 6: The CC Ease allows various functions to be programmed and displayed. Functions include setting additional ventilation programmes/options in the P menus. Users can read and set the day and time. The comfort temperature can be read and set. Ventilation volume can also be read and set. The CC Ease will return to the main menu automatically after 30 seconds. Users can activate the temporary high setting. There is an option to switch the supply and exhaust fan on/off. A personal ventilation programme can be set. Instructions for reading and setting the comfort temperature are provided.
• Page 7: Reading and setting the comfort temperature The comfort temperature can be set to the required indoor temperature. Based on this temperature, the ComfoAir will then automatically switch to free cooling using the bypass if required. It is best to set the comfort temperature to the same temperature as the room thermostat. Reading and setting the ventilation volume The actual ventilation level will always be displayed on the CC Ease. The ComfoAir regulates the required ventilation levels automatically in accordance with a preset ventilation programme. During automatic ventilation mode, AUTO will be displayed on the CC Ease. A temporary control system may override the ventilation setting. If a required ventilation setting is being overridden by a time delay function, a t is displayed on the CC Ease.
• Page 8: The ComfoAir will switch to the highest ventilation position set in the house unless overruled by an automated software programme. Setting 1 is for low ventilation levels. Setting 2 is for normal ventilation. Setting 3 is for high ventilation. The ventilation level can also be set manually by adjusting it higher or lower. A total of 4 ventilation volumes/levels can be set. The timer setting is for temporary high ventilation. Setting A is used when the house is unoccupied. At level A, the house is ventilated using the minimum prescribed ventilation volume. AUTO setting and MANUAL setting can be adjusted.
• Page 9: Temporarily activating high setting. Start temporary high setting. Once the programmed time delay is complete, the ComfoAir automatically switches back to the former ventilation setting. The timer of the temporary high setting can be switched off early by pressing specific buttons.
• Page 10: Switching supply and exhaust fan on/off (optional) While the open fire programme is activated, the supply and exhaust fan cannot be manually switched off. Bear in mind that switching off the supply or exhaust fan will temporarily immobilize your dwelling’s balanced ventilation system. Supply fan switched off Exhaust fan switched off Supply and exhaust fans switched on Switch supply/exhaust fan on/off < 2 sec.
• Page 11: Setting ventilation programme includes options for separate days and specific day combinations. The ventilation profile stage can be adjusted with a moment setting from 1 to 8. Selecting the hour and minute for the ventilation setting is required. The ventilation setting will flash to indicate it is ready to be saved. There is an option to define a new setting. AUTO mode can be selected for automatic operation. Choosing factory reset will revert to the default ventilation programme. The document provides instructions for saving and sorting settings. Flashing indicators are used to signify selection and adjustment processes. The user can delete a ventilation profile stage if needed.
• Page 12: Resetting malfunctions Reset error messages or filter dirty Programme mode End programme mode Start programme mode Using P menus User P menu (P1, P2, P9) Installer P menu (P1-P9) To perform a factory reset in P75, press and hold for 5 seconds. Select value = fast-set
• Page 13: P menus The ComfoAir installer manual states which functions are supported. Not all functions are supported by every ComfoAir. This might result in certain P menus not being visible. Menu P1: Status of programmes Menu P2: Setting time delays Activation delay for the bathroom switch switches to the high setting. Deactivation delay for the bathroom switch switches to the normal setting. Only applies to systems fitted with a corded switch and a second switch in the bathroom.
