Instructions for installation and use VX Solo II substations
4.0 Enduser instructions, General
Instructions
Please read these instructions carefully before installing and commis­sioning this substation. The manufacturer accepts no liability for loss or damage resulting from failure to comply with these instructions for use. Read and follow these instructions carefully to prevent the risk of physical injury and/or damage to property. Exceeding the recommended operating parameters appreciably increases the risk of personal injury and/or damage to property.
Warning! Hot surfaces
Parts of the substation may be very hot and can cause burn in­juries. Be very careful when you are in the immediate vicinity of the unit.
Installation, commissioning and maintenance must be carried out by qualied and authorised personnel (both plumbing and electri­cal work). Once the station has been installed and is operating, there is nor- mally no need to alter the settings or other functions. The district heating substation is very reliable and easy to operate.
For more detailed information about the substation, see the sec­tions concerning installation and commissioning.
Description
These instructions apply to substation types VX Solo II, which are dis­trict heating substations for indirect heating for single-family houses, semi-detatched and terraced houses as well as ats. With one or two heating circuits for radiator and/or oor heating and with connec­tion pipes for domestic hot water cylinder on primary or secondary side. For wall-mounting and with variable connection possibilities.
The HE supply temperature is controlled either by a self-acting ther­mostat T°C 200 or by a Danfoss ECL controller in combination with an electronic actuator. The ECL controller acts as the brain of the heating system. It lets you easily control and optimise system performance and operation.
We recommend regular inspections of the substation - ideally in connection with readings of the district heating meter. Pay special attention to any leaks and an excessively high return temperature in the district heating circuit (poor cooling of the district heating water). Cooling – i.e. the dierence between the supply and return temperature of the district heating water – has a signicant ef­fect on the overall energy economy. Therefore, it is important to focus on the supply and return temperature in the heating system. The dierence should typically be 30–35°C in systems that operate with radiators. In systems that feature oor heating, the dierence is typically 5–10°C. In these systems, it is important that the supply temperature does not exceed 35°C.
Warnings about high pressure and high temperature
The maximum supply temperature in the district heating net­work can be up to 120°C and the operating pressure can be up to 16 bar. This may result in a risk of scalding from touching the substation and from outow of the medium (water/steam). Ex­ceeding the substation design data and operating parameters for pressure and temperature carries an appreciable risk of personal injury and/or damage to property.
Emergencies
In the event of re, leaks or other hazards, immediately shut o all sources of energy to the substation, if possible, and call for appropriate assistance. If the domestic hot water is discoloured or malodorous, shut o all ball valves on the substation and the storage cylinder, notify all users and call for professional assistance without delay.
Irregularities
When reading the meters, check all joints and connections for leaks.
If you identify any irregularities/leaks, contact your professional provider for assistance. Check the troubleshooting section before contacting your professional provider.

Instructions for installation and use VX Solo II substations
5.0 Enduser instructions, Adjustment and Setting
Heating circuit, Dierential Pressure Controller
The dierential pressure controller (Fig. 1) reduces the high, uctuat­ing pressure in the district heating network to a constant operating pressure. The AVPL dierential pressure controller is initially set by the plumb- er in connection with the commissioning of the substation. If disrup­tions to the operation occur: noise in the radiator thermostats or poor regulation capacity, it may be necessary to reset the dierential pressure controller to a lower or higher operating pressure. We sug­gest that you contact your local plumber for assistance. The TD200 dierential pressure controller is preset from factory and should not be adjusted afterwards. The AVPB-F dierential pressure controller is preset from factory and should not be adjusted afterwards. The controller has a control valve with adjustable ow restrictor and ow setting is being done by the adjustment of the ow restrictor position. We suggest that you con­tact your local plumber for assistance.
Heating circuit, Temperature control
Thermostatic control
The supply temperature to the substation can be set by adjusting the thermostat TC (Fig. 2), which controls the temperature for the heating circuit. The thermostat will be set by the installer in connection with the com­missioning, but it may be necessary to adjust it subsequently depend­ing on the outdoor temperature.
Approximate thermostat scale setting: Pos. 1 = 20°C 2 = 30°C 3 = 40°C 4 = 50°C 5 = 60°C 6 = 70°C
Please note that a label on the TC thermostat will indicate the temperature range.

NB! For houses that are heated exclusively with oor heating. The supply temperature should typically be set to approx. 30–35°C. ALWAYS refer to the instructions from the oor supplier.
Other variations with other types of thermostatic valves for control of the heating circuit may occur.
Electronic control
The temperature for the heating circuit can be controlled electroni­cally by either a Danfoss ECL 210 or a Danfoss ECL 310 controller (Fig.
3). The supply temperature ist calculated by the controller on basis of the outdoor temperature. See the enclosed documentation for same.
Pump. VX S olo II substations are factory tted with pump(s) (Fig. 4). The pump setting is established in connection with the commissioning. Gene­rally speaking, this setting is not to be altered. If it should nevertheless be necessary to change the pump setting, see the section concerning pumps in the installation and commissioning sections regarding the individual products. In the summer, you can switch o the power to the pump at the mains if you want to save electricity by not heating your home. Start-up and venting – see the installation and commissioning sections, if necessary.

Instructions for installation and use VX Solo II substations
6.0 Installation instructions, Safety and Handling
Instructions
Please read these instructions carefully before installing and comis­sioning this substation. The manufacturer accepts no liability for loss or damage resulting from failure to comply with these instructions for use. Read and follow these instructions carefully to prevent the risk of physi­cal injury and/or damage to persons and property. Exceeding the re­commended operating parameters considerably increases the risk of personal injury and/or damage to property. Installation, commissioning and maintenance must be carried out by qualied and authorized personnel in compliance with the local safety regulations.
Once the station has been installed and is operating, there is normally no need to alter the settings or other functions. The district heating substation is very reliable and easy to operate.
Connection
It must be possible to cut o all energy sources to the unit - includ­ing electrical connections - at all times.
Potential equalization/grounding
Potential equalization is an electrical equalizer connection to secure against user contact with dangerous voltage, which may occur for example between two piping systems. Potential equalization re­duces corrosion in heat exchangers, water heaters, district heating units and plumbing installations. Equalization of potentials should be eected according to local regulations.
Energy source
The substation is primarily designed for connection to district heating. Alternative energy sources can be used if the operating conditions are equivalent to district heating at all times.
Application
The substation is designed only to heat water and other heating media may not be used. The substation is to be connected to the household piping in a frost-free room, where the temperature does not exceed 50 °C and the relative humidity is not higher than 80%. The substation must no be covered, bricked in or otherwise cut o from access.
Choise of materials
Only use materials, that comply with local regulations.
Corrosion
The maximum chloride compounds of the medium must not be higher than 300 mg/l. The risk of corrosion increases considerably if the recom­mended chloride content is exceeded.
Safety valve(s)
Installation of safety valve(s) must always be in compliance with local regulations.
Noise level.
≤ 55 dB.
Storage
Before installation, the units must be stored in a dry, heated (i.e. frost­free) room. (Relative humidity max. 80% and storage temperature 5-70 °C).
The units must not be stacked higher than the limit at the factory (max. 8 layers) Units supplied in cardboard packaging must be lifted using the handles incorporated in the packaging. Units must be placed on pallets for transport/moving across large distances. As far as possible, do not lift the substation by the pipes. Lifting by the pipes may cause leaks. REMEMBER to retighten.
Warning! Hot surfaces
Parts of the substation may be very hot and can cause burn inju­ries. Be very careful when you are in the immediate vicinity of the substation.
Warning of high pressure and high temperature
The maximum supply temperature in the district heating network can be up to 120°C and the operating pressure can be up to 16 bar. This may result in a risk of scalding from touching the substation and from outow of the medium (water/steam). Exceeding the substation design data and operating parameters for pressure and temperature carries an appreciable risk of personal injury and/or damage to property.
Emergencies
In the event of re, leaks or other hazards, immediately shut o all sources of energy to the substation, if possible and call for appropri­ate assistance. If the domestic hot water is discoloured or malodorous, shut o all ball valves on the substation, notify all users and call for professional assistance immediately.
Warning of damage during transport
On reception of the substation, and before installing it, check for any evidence of damage during transport. The substation must be handled and moved with the greatest care and attention.
NB! - Tightening of connections
Before mounting of the substation, ALL pipe connections MUST be retightened, as vibrations during transport may have caused leaks. Once the substation has been put into operation ALL pipe connections MUST be pressure tested for leaks and retightened once more if necessary. DO NOT OVERTIGHTEN THE PIPE CONNECTIONS – see page 19, “Test & connections” for more information.
Disposal
Dispose of the packaging in accordance with the local regulations for disposal of used packaging materials.
The substation is made of materials that cannot be disposed of together with household waste. Close all energy sources and disconnect all connection pipes. Disconnect and dismantle the product for disposal in accordance with the applicable local regulations for the disposal of the individual components.

Instructions for installation and use VX Solo II substations
8.0 Description of VX Solo II
VX Solo II are district heating substations for indirect heating for single-family houses, semi-detatched and terraced houses as well as ats. With one or two heating circuits for radiator and/or oor heating and with connection pipes for domestic hot water cylinder on primary or secondary side.
As standard the substations are supplied with tting piece(s) for mounting of heat meter(s).
The VX Solo II substations are available in various variants, - please see photos to the right.
The supply temperature to the heating circuit can be regulated by a self-acting thermostatic valve (type VX Solo II (T°C). In rooms with oor heating, the temperature is regulated using the oor heating thermostat for the room in question. In rooms with radiators, the temperature is regulated using the radiator thermostats.
Alternatively, the heating circuits can be regulated using fully auto­matic Danfoss ECL weather compensation equipment, - a Danfoss ECL controller in combination with electronic actuator(s). The ECL controller acts as the brain of the heating system. It lets you easily control and optimise system performance and operation.
VX Solo II (T°C) VX Solo II H (ECL 210/A230)
VX Solo II H2 (ECL 210/A260)
VX Solo II HWP (ECL 210/A237))
VX Solo II substations are also tted with pump(s).
As an option the VX Solo II substations can be equipped with a ther­mostat with safety monitor.
The VX Solo II variants are designed for wall mounting and oer vari­able connection possibilities as connection of pipes can be made both in top or bottom of the substation.
General information
PLEASE NOTE! Some models may have a slightly dierent appearance, as variants with other components may be supplied. Supplier instructions for the tted components will always be supplied together with the substation.

9.0 Installation instructions, general
The installation, connection and maintenance of the substation must be performed by qualied and authorised personnel. Installation must always be performed in accordance with the ap­plicable legislation and in compliance with these instructions. The substation must be installed so that it is freely accessible and can be maintained without unnecessary disruption. Lift the substation by its mounting plate and secure it to a solid wall using 2 expansion bolts or the like positioned in the two keyholes in the mounting plate.
We recommend positioning of rubber spacers between the wall and the unit to prevent the transfer of resonance noise from the pump into the wall.
Before commissioning, rinse all the pipes in the household piping system thoroughly to remove any impurities, and check and clean the dirt strainers in the substation. Connect the substation to the household piping in accordance with the labelling at the bottom and/or in accordance with the instruc­tions in this manual.
Test and connections
Before lling the system with water, retighten all the pipe connections because vibrations and shocks during transport and handling may have caused leaks. Once the system has been lled with water, tighten all the pipe connections once more before performing pressure test for leaks. After heating of the system, check all the connections and retighten if necessary. Please note that the connections feature EPDM rubber gaskets!
Therefore, it is important that you DO NOT OVERTIGHTEN the union nuts. Over-tightening may result in leaks. Leaks caused by over-
tightening or failure to retighten connections are not covered by the warranty.
Variable connections possibilities
The substations oer variable connection possibilities, as connec­tion of pipes can be established in the top or in the bottom of the substation. Upon delivery the substation is prepared for connection in bottom of the substation. For change of connection from bottom to top, demount plugs on connection pipes in top of substation and ball valves on connection pipes in bottom of substation, and mount plugs in connection pipes in bottom of substation and ball valves on connection pipes in top of substation. Please note that the air screw, which originally is mounted on the heating supply pipe in top of substation must be relocated to the highest point of the substation.
PLEASE NOTE that the variable connection possibilities makes it possible to establish some of the connections in the top and others in the bottom of the substation. This may be desirable in some cases.
Safety valve
Always lead the blow-o pipes from the safety valves to a drain in accordance with applicable legislation.
Expansion vessel
The VX Solo II substations are equipped with an expansion vessel, which is factory set to 0,5 bar.

General information
PLEASE NOTE! Some models may have a slightly dierent appearance, but the control function is in principle the same as described below.
Commissioning
Commission the unit in accordance with the instructions on pages 17-21.
Filling the system
Filling of water to the heating system must be done through con­nection to an exterior cold water supply. Check and tighten all connections before adding water to the system, as vibrations during transport may have caused leaks. After having added water to the system, tighten all the connections before per­forming leak test. Then heat up the system, check the connections and tighten once again if necessary.
Before adding water to the system and rst start-up, check if:
- pipes are connected according to the circuit diagram,
- expansion vessel is connected,
- heat meter is mounted,
- shut-o valves are closed,
- threaded and anged connections are tightened.
Filling - (Note, by means of exterior cold water supply):
If the pressure drops below 1 bar, water must be added to the system. The operating pressure should never exceed 1.5 bar.
(The safety valve opens at 3 bar)
1. Pump must be switched o when water is added to the system.
2. Fill heat exchanger and system with water until the manometer shows a working pressure, which corresponds to the system height + 5 m (approx. 1.5 - 2.0 bar)
3. Vent the system completely.
4. Start the pump.
5. For substations, which include zone valve, remember to remove the red split on the position indicator of the zone valve.
If system pressure drops dramatically within a short time, heating system should be examined for leakage, - this includes checking the factory set pressure of the expansion vessel.
Dierential pressure controller
(Standard on systems with self-acting thermostatic valve). The dierential pressure controller reduces the uctuating pressure in the district heating network to a small and invariable operating pressure in the substation. The required room temperature is controlled on your radiator ther­mostats.
Dierential pressure controller AVPL
AVPL is a self-acting dierential pressure controller for PN 16 with adjustable dierential pressure setting and the dierential pressure controller can be set at any dierential pressure between 5 kPa and 25 kPa (0.05 bar and 0.25 bar). The preset factory setting of the controller is 10 kPa (0.1 bar). The dierential pressure can be set by means of an Allen key NV 3. 1 turn corresponds with 1 kPa (0.01 bar).

11.0 Adjustment and commissioning, heating circuit
The temperature for the heating circuit can be controlled by a thermostatic valve T°C 200.
Approximate thermostat scale setting: Pos. 1 = 20°C 2 = 30°C 3 = 40°C 4 = 50°C 5 = 60°C 6 = 70°C
Please note that the values are intended as a guide and may vary according to the district heating operating conditions. Approximate supply temperatures at: 10 °C outdoor temperature approx. 40°C 0 °C outdoor temperature approx. 55°C
-10 °C outdoor temperature approx. 65°C
It is important to keep the supply temperature to the radiators as low as possible (the temperature is indicated by thermometer mounted in HE return). The room temperature is controlled by radiator ther­mostats.
Floor heating (substation with heat exchanger for oor heating). It is important to keep the supply temperature to the oor heating system as low as possible, approx. 30-35° (the temperature is indi­cated by thermometer mounted in HE supply),
The T°C is typically set in pos. 2-2.5 (intended as a guide). The supply temperature should not exceed 40°C (ALWAYS refer to the instruc­tions of the oor supplier).
Please note that a label on the TC thermostat will indicate the temperature range.
Zone valve / thermal actuator TWA-A (option)
The thermostatically controlled VX Solo II can as option be equipped with zone valve/thermal actuator TWA-V, which enables connection to an electronic programmable room thermostat.
The thermal actuator of the zone valve is switched on by an exter­nal contact from the room thermostat, and starts to open or close the valve. The actuating movement is achieved by means of an electrically heated expansion element. When the heating current is switched o, the actuator shuts or opens the valve.
The actuator is equipped with a visual position indicator to show the open or closed position of the valve. Heating operation is then activated by the programmable room ther­mostat in connection with a zone valve /thermal actuator TWA-A.
Electronic programmable room thermostat (option)
If the substation is connected to a room thermostat the tempera­ture is controlled by the room thermostat and radiator thermostats. Please note that the room thermostat keeps the temperature at a constant level in the whole apartment according to the set room parameters. Consult additional maintenance instructions for room thermostat for further information. It is recommended to avoid fully opened thermostats on some radiators and fully shut-o on others. Higher temperature at the top and lower temperature at the bottom part of radiators means that the system operation is correct.

15.0 Maintenance
Maintenance work
Is only to be carried out by qualied and authorised personnel.
Inspection
The substation should be checked regularly by authorised personnel. Any necessary maintenance must be performed in accordance with the instructions in this manual and other sets of instructions. During service the dirt strainers are to be cleaned – including the lter on the controller, all pipe connections must be tightened and the safety valve must be function tested by turning the lever.
Rinsing/cleaning of plate heat exchanger
To clean the plate heat exchanger, rinse it by running clean water through the exchanger at high speed and in the opposite direction to the normal ow. This will remove any dirt deposits that may have built up in the exchanger. If rinsing with clean water is not sucient, the exchanger can also be cleane d by circulating a cleaning agent approved by Danfoss (e.g. Kaloxi or Radiner Fl cleaning uid) through the exchanger. Both these cleaning uids are environmentally friendly and can be disposed o through the standard sewer system. After use of a cleaning uid, the plate heat exchanger must be rinsed thoroughly with clean water.
Acid cleaning of plate heat exchanger
Deposits of limesc ale may build up in plate heat exchangers for domestic hot water on account of the large temperature uc tuations, and because aerated water is used on the secondary side. If it becomes necessary to clean the exchanger with acid, this can be done as shown on the drawing to the right. Brazed plate heat exchangers can withstand rinsing with a dilute acid solution - e.g. 5% formic, acetic or phosphoric acid).
Measures after maintenance work
After maintenance work and before commissioning: – Check that all screwed connections are tight. – Check that all safety features, covers, that were removed, have been
replaced properly. – Clean the working area and remove any spilled materials. – Clear all tools, materials and other equipment from the working area. – Connect to energy supply and check for leaks. – Vent the system. – Carry out any necessary adjustment again. – Make sure that all safety features on the device and the system work
properly.
Meter reading
The caretaker/owner must perform visual checking and reading of the district heating meter at short, regular intervals. (The meter is not a part of the delivery from Danfoss). Service procedures must only be performed by trained, authorised personnel. NB! Excessive consumption for whatever reason is not covered by the Danfoss warranty.
Cooling / Return temperature reading
Cooling – i.e. the dierence between the supply and return temperature of the district heating water – has a signicant eect on overall energy economy. Therefore, it is important to focus on the supply and return temperature in the heating system. The dierence should typically be 30–35°C. Please note that a low district heating return temperature is directly related to the return temperature from the heating circuit and the return temperature of the circulation water. It is therefore important to focus on these return temperatures.

18.0 Commissioning Certicate
Commissioning certicate
The substation is the direct link between the district heating supply network and the household piping system. All supply pipes and the pipes in the household piping system must be checked and rinsed before commissioning. Once the system has been lled with water, all pipe connections must be retightened before performing pressure test for leaks. The dirt strainers must be cleaned and the substation must be adjusted in accordance with the instructions in this manual.
It is important to comply with all technical regulations and the applicable legislation in every respect.
Installation and commissioning must only be performed by trained, authorised personnel.
The substation is checked in the factory for leaks before delivery. Leaks are however possible due to vibrations caused by transport, hand­ling and heating of the system and therefore it is important to check all connections and to retighten if necessarys before commissioning. Please note that the connections may feature EPDM gaskets! Therefore it is important that you DO NOT OVER-TIGHTEN the connections. Over-tightening may result in leaks. Leaks caused by ove-rtightening or failure to retighten connections are not covered by the warranty.
To be lled-out by the installer.
This substation has been retightened, adjusted and commissioned
