manual Before installation the user should be thoroughly familiarized with this user manual, especially with purposes, installation, settings and operation. Special care should be taken when installing and connecting external equipment (sensor, high voltage etc.) and handling the PCB’s correctly according to protection against ESD Installation of the electronics/parts must be performed by authorized personnel only. All warranties are excluded in case installation is performed by unauthorized personnel or in case the spare parts have not been correctly installed. 3|Page 393930-2 Rev 0: 01.04.2020 2 Functions of the Air Handling Unit Controller The Air Handling Unit controller is designed for domestic and smaller industrial ventilation systems. Heat recovery can be either passive or active using a heat pump. Air heater can be added to either pre-heat or after-heating the inlet air. The air handling unit can also be extended with hot tap water production using a heat pump taking

energy from the exhaust air. Depending on the complexity and size of the ventilation system the following functionality is available: • Ventilation control • Temperature control • Heat recovery – via rotor heat exchanger • Air heater – after-heater • Defrosting • User functions • Week program • External heat source control • Filter monitoring via pressure-drop measurement (optional) 2.1 Ventilation control 2.1.1 Start-up Unit with outputs for air dampers can be configured for a delayed start of the ventilation fans. This gives the air dampers time to be fully opened before pressure builds up. Via a menu the ventilation start delay can be adjusted. Inlet starts another 1 minute after the exhaust fan has started. If low winter ventilation is activated, the unit will always start up at the selected winter low step the first 2 minutes. 2.1.2 Ventilation based on humidity and CO2 level A humidity sensor (included) and a CO2 level sensor (optional) can be connected

to the unit controller. The controller will adjust ventilation based on the desired settings in the Air quality menu. The installer configures the humidity levels where ventilation should change speed either up or down. NOTE! REMOVE THE DUST CAP FROM THE SENSOR AFTER THE UNIT WAS INSTALLED!!! In the same menu the settings for ensuring a comfortable CO2 level can be configured. There are two CO2 levels, a normal level and a high level where the ventilation speed will be increased. Both sensors have 3 minutes settling time after start from ventilation step Off. Average = 24 hours average. RH (high) = Average + 10%; RH (low) = average + 3% 2.2 Temperature control 2.2.1 Low room temperature alarm This function ensures the room temperature is not getting too cold. If the room temperature is getting below the room low-temperature limit, the inlet speed is reduced 1 step. After 5 minutes the speed is reduced again until temperature can be maintained. If the room temperature cannot be main

tained, the fans are stopped, and a Low Room Temp warning is set. An external room temperature sensor is mounted. The function can be disabled by setting the Room low limit to off in the Room control menu. 2.2.2 Summer/Winter operation The controller can automatically switch between summer and winter operation based on the outdoor temperature. After each shift, the unit stays here for 15 min before another shift is allowed. The difference between summer/winter operations is the minimum temperature of the inlet air and that the bypass damper is normally not opened in wintertime. 2.2.3 Control sensor The controller can use different controlling sensors. Supply: The inlet temperature sensor is used; there is no room temperature control. Extract: The extract temperature sensor is used. 4|Page 393930-2 Rev 0: 01.04.2020 2.3 Air heater (after-heater) The air heater (or after heater) heats up the air after the air has passed the heat exchanger. It must be enabled and configured in th

e Air heater menu. The heater can be None or Electrical. The electrical heater has a 0 – 10V analogue output and the heater relay is turned on when the heater is needed. 2.4 Defrosting Defrosting is done for 6 minutes every hour. During defrost, the supply fan is stopped, the exhaust fan is running at MIN speed, the air heater is off and rotor speed is normal. • Mode 1 is for low humidity and starts at -20⁰C • Mode 2 is for normal humidity and starts at -15⁰C • Mode 3 is for high humidity and starts at -10⁰C After defrosting, the air heater is first started when fans are up and running 2.5 User selection functions Activating the User function digital input can trigger different functions. The air handling unit will perform this operation during the selected period and overriding the other user settings including week program settings.

This ensures the rotor is first started when the rotor alone is insufficient. 2.8 Party mode The user can activate a party mode. It is used for increased ventilation with many people in the ventilated area. Fan speed is set to MAX, the user can set it to MIN or NORM afterwards. The existing set point is used. The user can change the set point during active party mode. Party mode is automatically stopped when the party timeout period is over. Default timeout is 4 hours, it can be changed after th

(Ensy Art no: 01008045-2) To avoid vibration from the unit towards building constructions it here is important that there are placed 5 mm vibration damper on the back of the unit. Two vibration gaskets screws for the extra bracket follow the extra bracket. One of the gaskets is placed in top of the unit. The other one you place approx. 60 mm from the button of the unit so that id do not will come in contact with the wall bracket. Then first put those two brackets in each end of the unit as shown on page 16. Then the wall bracket, with 10 mm gasket, is screwed to the wall where it is wanted. Use 8 pcs wood screws 5 x 40mm. Then you can lift the unit and place it on the wall bra

That way, you can adjust with the nuts so that the unit is in level. If so, then use the suspension brackets as jigs for the bolts so that the distance between brackets will be correct. Use correct drill for use for the M10 mm expansion bolts. If so, then use the suspension brackets as the bolts so that the distance between brackets will be correct. (On top dim. for AHU 300H and under dim for AHU 400H) Use correct drill for use of M10 mm expansion bolts. Make sure the bolt is turned so hard that it can not loosen. The bolts are available in different lengths so select someone s

these are due to isolate. Reasons for thermal insulation of ventilation ducts are: • • • obtain good heat economy by limiting heat loss achieve a specific outlet temperature of the ventilation air. preventing condensation on either the inside or outside of the duct. Heating costs reduced by preventing the heat supplied in ventilation air can be transferred to unheated surroundings. If the ducts are positioned in a cold environment, such as in an attic, where the temperature is significantly lower than the ventilation air, there is a risk of condensation inside the ducts. This can be prevented by isolating the channel exterior. It can also be used insulation tubes (100 mm mineral wool) with plastic diffusion barrier pulled over the ducts. The same applies to insulation of pipings between the unit and diffusors, bringing the cooled air up to the rooms. In areas with extremely low winter temperatures, additional insulation must be used. Total insulation thickness must be at least
