Compact S
Specifications & Technical Data
Compact S is an energy-efficient total indoor climate solution for all types of low-energy buildings, single-family homes, flats and small office areas in commercial leases with a ventilation requirement of up to 375 m3/h.
The heat pump has a reversible cooling circuit, which means that, in the summer, the unit can cool the supply air by up to 10 °C. Due to the low air exchange, the cooling does not function as an air conditioning system. On cooling, the supply air is dehumidified, which gives a more pleasant indoor climate than is possible with an ordinary ventilation unit without a heat pump.

AUTOMATION
The CTS602 comes with factory settings, including a default setting which can be customised to operational requirements to achieve optimum operation and utilisation of the system.
The operating panel must be placed in a dry, frost-free location, at least 1.5 m above floor level and at least 0.5 m from any corner. Avoid placing the panel on an external wall or in areas in direct sunlight.
Operating instructions for the CTS 602 can be found in a separate user manual supplied with the unit.

Functional overview |
+ Standard – Accessories |
|
3 levels | The control function is divided into 3 levels: User/Service/Factory with various options at each level | + |
Weekly plan | The unit has 3 weekly programmes (with a factory setting of “off”) • Programme 1: for working families • Programme 2: for stay-at-home families • Programme 3: for businesses There is also an option for you to set your own weekly programme. |
+ |
User option 1 | This allows you to override the operating mode in the main menu via an external potential-free contact or PIR sensor. | + |
User option 2 | With an Expansion PCB mounted, allows you to make additional connections, e.g. • User option 2 overrides User option 1 (e.g. connecting an EM box) • Up to 500 W direct • Output relai • Switching the central heating system on/off |
|
Alarms | Alarm log featuring the last 16 alarms. | + |
Filter monitor | Filter monitor with timer (factory setting of 90 days). Adjustable to 30/90/180/360 days. | + |
Bypass |
Bypassing the outdoor air reduces heat recovery, enabling the desired supply air temperature to be maintained spring, summer and autumn. | + |
Air quality | Allows you to choose whether to switch humidity sensors and/or CO2 sensors on and off. | +/- |
Humidity control | Allows you to set a higher or lower ventilation step in the case of high/low air humidity. | + |
Summer/Winter operation | Possible to set operation for summer and vinter | |
Winter low | Allows you to select a low ventilation step in the case of low outside temperatures | |
Defrost function | Temperature-based automatic function for defrosting the heat exchanger. | + |
Frost protection | In case of failing heating system, the unit is turned off to avoid further cooling with a risk of the water heating coil frost bursting. | + |
Temperature control | Allows you to select the temperature sensor which will control the unit. • T15 ROOM (panel sensor) • T10 EXT (fitted in a representative extraction valve) • T3 EXHAUST (extract air) |
+ |
Room low | Stops the unit at a low room temperature. Hereby is cooling of the home avoided in case of a failing central heating system. Standard set to OFF. Can be set from 1 to 20 degrees and is controlled by: • T15 ROOM (panel sensor) • T10 EXT (fitted in a representative extraction valve) • T3 EXHAUST (extract air) |
+ |
Air volume | Allows you to set four ventilation steps. Supply air and extract air are set individually. • Step 1 < 25% – Step 2 < 45% – Step 3 < 70% – Step 4 < 100% |
+ |
Legionella control | It is possible to choose a weekday or a day during the month, where the sanitary hot water temperature reaches 65 °C, for example between 1 and 6 o´clock. |
|
External firealarm | Possible to connect the unit to external firealarm. | |
Joint alarm | Outlet for joint alarm. | + |
Constant pressure control | Allows control from both the extract air and supply air side. | – |
Cooling | Via bypass (can only cool with outdoor temperature) and cool recovery (can only cool with indoor temperature). This allows you to choose whether to run the system at a higher or the highest ventilation step during cooling. The weekly programme has an option for setting cooling at night. |
+ |
Intake air control | Allows you to set the regulator to control the intake air temperature/supply air (only available if the control unit has been configured for a supply-heating element). |
+ |
External heating element | • Temperature sensor T7 is an supply air sensor • Integrated frost protection for external water heating element • Motorised valve and circulation pump control unit |
+ |
External electric heating element | • Temperature sensor T7 is an supply air sensor • Overheating protection |
