The Geo Module
Specifications & Technical Data
Compact P GEO has the same features and benefits as the Compact P, but can also use the energy stored in the ground to heat your home.
With help from ground pipes Compact P GEO uses and exploits the energy stored in the ground to heat your home using underfloor heating or other heating solutions at low temperatures. The system has an integrated 3 kW (Compact JVP 3) or 6 kW (Compact P GEO 6) geothermal pump. Both have a variable compressor which can be regulated 1.5-3 kW 2-6 kW (liquid/water temperature of 0°/35°C). This means that the solution adapts the need for heatinh, thus ensuring low power consumption.
Compact P GEO solution can reduce your heating bill by up to 50%. For each kW of electricity the geothermal heat pump uses, you will get up to four kW back.

TECHNICAL DATA
Compact P GEO offers the same benefits and functions as Compact P, but additionally has an integrated geothermal pump, with connection to waterborne underfloor heating or low-temperature central-heating radiators. The heat pumps are available in two sizes: GEO 3 (0.5 – 3 kW) and GEO 6 (1 – 6 kW). The variable compressor makes Compact P GEO a far more efficient and energy-friendly solution than traditional heat pumps that often have compressors with a constant output. As the output is subject to variable regulation, the heat pump never uses more energy than necessary, which gives a very high SCOP. With GEO 3, a SCOP of 5.17 is achieved.

AUTOMATION
The CTS602 control is an advanced control with many setting options. The control is delivered from the factory with a basic setting that can be adapted to the operational wishes and requirements, in order to achieve optimal operation and utilization of the unit.
The HMI Touch panel provides a good overview of the unit’s current operation, and has a menu structure that is easy to navigate for both user and installer.
External communication
The CTS602 control has an open Modbus RS485 protocol that can be used to communicate with via external CTS systems. The Modbus connection is used e.g. for Schneider’s IHC or KNX system.

| Function overview | +Standard -Accessories |
|
| Filter guard | The time-controlled filter guard notifies you when it is time to change the filter. Can be set between 30 and 180 days. | + |
| Operating mode | Can be set to run Auto according to set values or set to run in heating or cooling mode. | + |
| Stepless regulation | The four ventilation stages can be set steplessly 20-100%, with different values for supply air and extract air. | + |
| Moisture management | Built-in humidity control can be set to run high ventilation mode when there is high humidity (when you are in the shower) and low ventilation mode if the humidity in the home becomes too low. | + |
| Active cooling | The unit can be set to cool the supply air in the summer if needed. When the heat pump cools, the heat is deposited in the hot water tank, so that you get “free” hot domestic water when the unit is in cooling mode. | + |
| Low outdoor temperature | It is possible to lower the ventilation when the outside temperature is low, to avoid that the humidity inside becomes too low. | + |
| CO2 management | It is possible to control the ventilation level according to the home’s CO2 level. | – |
| 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 if ice should form in it. | + |
| Frost protection Polar | The Polar model has a built-in anti-freeze pre-heater to protect the counter-flow heat exchanger so that it does not get ice. | + |
| Frost protection EHD | The control can control an EHD damper, which is used if the outside air comes via a roof hood. | + |
| Hot domestic water | Compact P produces the hot domestic water via the air/air heat pump in the ventilation part. | + |
| Pause domestic hot water | It is possible to pause hot water production if, for example, for a period not at home. In this way, energy is saved. | + |
| Antifreeze hot water | To protect the hot water tank, it is equipped with a frost protection function. | + |
| Electricity supplement hot water |
If the demand for hot water is so great during periods that the heat pump cannot keep up, an electric supplement can be switched on to help heat the hot domestic water. |
+ |
| Scalding protection | The control has a built-in scalding protection, which ensures that the hot domestic water does not become too hot and could scald the users. | + |
| Anti-Legionella | The control has an Anti-Legionella treatment of the hot domestic water, which can be activated manually or automatically. | + |
| Anode | Electronically monitored anode. Notifies when it’s time to replace it, extending the life of the hot water tank. | |
| SHW preheating tank | An additional hot water tank SHW can be connected to the GEO geothermal heat pump and preheat the hot domestic water to 45 ºC before it enters the Compact P hot water tank. | + |
| Hot domestic water | If the Compact P is ordered with a solar coil, the GEO ground source heat pump can be connected to the Compact P hot water tank and help produce the hot domestic water. A good solution if there is a large need for domestic hot water and there is no space for a SHW container. | + |
| Weekly schedule | A weekly plan can be made with different settings depending on the use of the home. | + |
| Smart Grid | Compact P GEO is approved for Smart Grid solutions, where the electricity company determines the electricity consumption and thus the operating costs. | + |
| User selection 1 | Used if you want to override the unit’s operation via a potential-free signal. Used e.g. if an extractor hood is connected to the system. | + |
| User choice 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. | + |
| Event log | Logs events in the control as well as error messages and warnings. | + |
| Read out data | All current values in the plant’s operation can be read out. Most often used for troubleshooting. | + |
| Emergency stop ventilation | You must not switch off the ventilation, as this can cause damage to the unit, duct system and, in the worst case, the home. But it may be necessary to briefly switch off the ventilation, e.g. due to an emergency notification. | + |
Further information about all the functions can be found in the unit’s Software and Assembly instructions.
