Compact P AIR9 PROPANE

Compact P is a multi-unit with three installations that are combined in one compact installation. It is intended for large dwellings with a ventilation requirement of up to 275 m3/h. The three installations comprise ventilation of the dwelling, production of domestic hot water, and heating of the dwelling via an efficient air to water heat pump.

By integrating all three installations in just one installation, you save considerable space in the machine room. Another advantage is that the control systems work in unison, which enables energy efficiency and thereby an overall saving in energy consumption. 

The outside unit AIR 9 Propane is delivered with a reversible heat pump, which also makes the unit capable of cooling.

AIR 9 Propane is very silent and can be placed without disturbing it surroundings. During summer, when only hot sanitary water is needed, the fan is limited, reducing the noise level. This limit occurs when the outdoor temperature exceeds 7 °C and limiting the compressors output to a maximum off 60 %. These criterias can be set individually.

Propane R290 is a green refrigerant that is already to be found in nature and is therefore considered a CO2-neutral refrigerant.

AIR9 (outside part)

The CTS602 control system is an advanced control system with many settings options. The control system is supplied with factory default settings that can be adapted to the operational requirements in order to achieve best possible operation and utilisation of the unit.

The HMI Touch panel provides an overview of the current operation of the unit. The structure of its menu makes it easy to navigate for both user and installer. You can choose from 2 different images for the main screen.

External communication
The CTS602 control system has an open Modbus RS485 protocol that can be used for communication via external CTS systems. The Modbus connection is used for e.g. Schneider's IHC or KNX systems.

Functional overview   +Standard
-Accessories
Filter monitor Filter monitor with timer notifies when it is time to change filters. Can be set between 30 and 180 days. +
Operating mode Can be set to Auto according to set values or set to heating or cooling mode. +
Stepless regulation The four ventilation steps can be set steplessly 20-100%, with various values for supply air and exhaust air. +
Humidity control Built-in humidity control can be set to high ventilation operation at high humidity (when in the shower) and low ventilation operation if the humidity in the home becomes too low. +
Active cooling The unit can be set to cool the supply air in the summer, should the need arise. When the heat pump cools, the heat is deposited in the hot water tank, so that you get “free” hot water when the unit is in cooling mode. +
Low outdoor temperature It is possible to lower the ventilation at low outdoor temperature, to avoid the indoor humidity becoming too low. +
CO2 control It is possible to control the ventilation level according to the CO2 level in the home. -
Temperature settings The temperature settings are used by the controller to regulate the operation of the entire system. +
Frost protection The control has an automatic function for defrosting the heat exchanger to prevent formation of ice. +
Frost protection Polar The Polar model has a built-in frost protection preheater to protect the counterflow heat exchanger so no ice occurs. +
Domestic hot water Compact P produces the domestic hot water via the air / air heat pump in the ventilation part. +
Pause domestic hot water It is possible to set the hot water production on pause e.g. if no one is at home. In that way, energy is saved. +
Frost protection domestic hot water To protect the hot water tank, it is fitted with a frost protection function. +
Supplementary electrical heater domestic hot water

If the need for domestic hot water increases and the heat pump cannot keep up, a supplementary electrical heater can be activated to heat the domestic hot water.

+
Anti-scald protection The control has a built-in scalding protection, which prevents scalding of the users when the hot water tap is opened. +
Anti-Legionella The control has an Anti-Legionella treatment of the domestic hot water that can be activated manually or automatically. +
Anode Electronically monitored anode. Notifies when it is time to replace it to ensure a long service life of the hot water tank.  
SHW tank An additional hot water tank SHW can be connected to the air/water heat pump and preheat the hot domestic water to 45 ºC before it enters the Compact P hot water tank. +
AIR domestic hot water
If you order Compact P with a solar coil, you can connect the air/water heat pump to the Compact P hot water tank. The heat pump can then help produce domestic hot water. This is a good solution if the requirement for domestic hot water is high and there is insufficient space for an SHW tank.
+
AIR heat pump on/off If the air/water heat pump is not to heat the dwelling for a period of time, it must be switched off manually. +
Cooling/heating simultaneously The control system ensures that the air/water heat pump cannot heat the dwelling when Compact P is in cooling mode. However, if you still want e.g. the bathroom floor to be warm in the summer, you can set the control system to cool and heat simultaneously. Compact P will then no longer prevent the air/water heat pump from providing heat. +
Weather compensation The flow temperature can be set to follow the outdoor temperature. +
Week program You can set up a week program with different settings depending on how much the dwelling is being used. +
Smart Grid Compact P AIR is certified in accordance with the German Smart Grid, which allows the electricity provider to override the operation so it becomes as cost effective as possible for the user. +
User selection program 1 A user selection program enables you to use special settings that override the standard operating settings via a potential-free signal. Used e.g. if a cooker hood is connected to the system. +
User selection program 2 Used as user selection 1, but at the same time has an output signal that can be used e.g. to control a damper. +
Datalog Data Data logging as well as error messages and warnings. +
Output data All current values in the system operation. Most often used for troubleshooting. +
Emergency stop ventilation Do not turn off the ventilation, as this may damage the unit, duct system and in the worst case the home. But it may be necessary to briefly turn off the ventilation e.g. due to a emergency notification. +

You can find further information about all the functions in the Software and Installation instructions for the unit.

 

PHI certificate

Compact P has been certified in accordance with the German PassivHaus Institute for energy friendly products.

Smart Grid

Compact P has been certified in accordance with the German Smart Grid, which allows the electricity provider to override the operation so it becomes as cost effective as possible for the user. 

The Smart Grid solution can also be used in connection with solar cells if you want to optimise operation at times when most energy is being produced.
