1 Important Information * If the installation will be shut down during the winter months, the heating system should be emptied of water to avoid any damage due to freezing.(Call your Installation Contractor for help, see ”References” on page 30). * The installation is practically maintenance free, but some monitoring will be required (see ”Operating Instructions” on page 7). * Before making any adjustments of system parameters, first find out, what the consequences are in each case.
an immersion heater. The Tap Water Stratification system improves the efficiency of heat transfer by keeping the water in distinct thermal layers in the water tank. The unit is fitted with a regulating computer, which is controlled over a graphic display unit. Heat is distributed throughout the house over a hydronic heating system referred to as low temperature system with a maximal water temperature to radiators ( Feed line temperature) of 65°C.
. The heat pump has two separate liquid circuits circuit – circulating inside the heat pump. Through evaporation, compression and condensation it absorbs energy from the outdoor unit and releases it to the heat carrier. The refrigerant is chlorine-free. Refrigerant Heating circuit – water transporting heat energy to the heating system (radiators/floor coils) and the water heater.
AWA-SS 2.4 Control Panel The control panel of AWA-SS series features a graphic display, five control buttons. Beside the control panel you will find the User’s Manual, a short description of how to increase and reduce room temperature, and a label with name and phone number of dealer. ROOM 20 OPER.

Before the Degree Minute reach - 60 (adjustable) ,the compressor is off, but when the Degree Minute reach - 60 (adjustable) ,the compressor automatic start, and the flow temperature will begin increase. (Higher than desired temperature) when the actual water supply temperature reach / higher than the desired temperature, the DM will be changed. For example : the DM was cumulated to -160 in this time. 1 minutes later when the Feed water temperature higher than desired temperature for 1ć.

LANGUANG ENGLISH DEUTSCH Use Up and Down botton to select the language ,and press Right button to confirm. 3.2 Adjustments to be made rregularly Most settings will be made by the installation contractor in connection with installation.
CURVE is program that adjusts feed water temperature according outdoor ambient temperature, factory setting is ambient temperature 0ć as feed water temperature 40ć, that is CURVE =40; the value of CURVE is adjustable from 22ć to 56ć.
If you wish to change the ROOM value: 1 Press the ”up” or ”down” button once to open the ROOM value for adjustment. 2 Increase or reduce the preset value using the ”up” or ”down” button so that the desired room temperature is reached. Wait for 10 seconds or press the left-hand button once to return to the main menu. When enter ‘Room heat’ mode, user could control compressor and electrical heater through regulate heat curve or DM (degree minute).
3.2.4 Adjustment of Part of the Heat Curve At outdoor temperatures between -5°C and +5°C part of the heat curve may need adjusting if the indoor temperature does not stay at the preset ROOM value. For this reason, the control system includes a function adjusting the curve at three outside temperatures: -5°C, 0°C, +5°C. This function will allow you to increase or reduce the feed line temperature, without affecting the heat curve, at three specific outdoor temperatures.
If you wish to change a specific part of the heat curve: 1. Open the main menu INFORMATION by pressing the right-hand button once. You will find the cursor at the sub- menu OPERATION. 2. Press the ”down” button to move the cursor to the sub-menu HEAT CURVE. 3. Open the selected menu by pressing the right-hand button once. You will find the cursor at the parameter CURVE. 4. Using the ”up” or ”down” button, select either CURVE 5, CURVE 0 or CURVE -5. 5.
3.2.6 Adjustment of the HIGH T STOP and LOW T STOP ‘HIGH T STOP’ and ‘LOW T STOP’ functions are only for room heating, the water tank heating still works normally when the two functions are active. The HIGH T STOP and LOW T STOP function stops water production to room floor when the outside air temperature is equal to higher or lower than the value entered for HIGH T STOP or LOW T STOP. When the function is activated, the circulation pump will be turned off. The factory setting of the HIGH T STOP is 50°C.
3.3 Maximum Return Line Temperature The maximum return line temperature, i.e. temperature of the water returning from the heating system, should be adapted to each individual installation. The correct temperature value for your system will be entered by your installation contractor in connection with installation and can be adjusted later. 3.4 Warm Water Production The temperature of the water distributed to the water heater is controlled by the regulating pressure switch and cannot be adjusted.
Don’t use any water treatment additives for the heating system! 3.5.3 Checking the Safety Valves Both safety valves of the heating system should be checked at least four times a year to prevent lime deposits to clog the mechanism. To find out where the safety valves are located. The safety valve of the water heater protects the closed heater against positive pressure. It is fitted on the cold water inlet line, its outlet opening facing down- wards.
4 Trouble shooting 4.1 Alarm Messages In the event of an alarm message, try to re-start the unit with the safety switch. If this does not work, try to solve the problem with the help of the table below. Call your installation contractor if you need help. See ”References” on page 30.
5 Terminology and Abbreviations Evaporate In the evaporator, energy from the heat source is absorbed by the refrigerant passing through the evaporator. The refrigerant turns into gas. (See ”Heat Pump Principle” on p. 4). INTEGRAL INTEGRAL is the heat balance of the heating system. Production of heat is regulated acc. to a calculated heat demand value. This value is determined by comparing the actual supply line temperature with its calculated (setpoint) value.
6 Default Settings The first column of table 7 shows the parameters that are adjustable by the User. The second column shows settings made at the factory and the third column the settings made by the installation contractor in connection with installation of the heat pump. Make sure that the installation contractor enters any settings made during installation that are particular for your heat pump. This will make it easier for you when you make your own adjustments.
