Thanks to smart technology, the product gives you control over your energy consumption and will be a key part of your connected home. The efficient control system automatically adjusts the indoor climate for maximum comfort, and you do nature a favour at the same time. • Three output sizes and leading inverter technology for optimum customisation. • Optimal seasonal performance factor and minimal operating costs. • Energy-saving smart technology with user-friendly control for maximum c

This is how F1255 works Installation method Rock F1255 collects a proportion of the rock’s stored solar energy via a collector in a borehole in the rock. F1255 collects a proportion of the water’s stored solar energy via a lake collector that is anchored on the lake bed. F1255 collects a proportion of the ground's stored solar energy via a buried ground collector.

F1255 is equipped with a 180 litre water heater, which is optimally insulated for minimal heat loss. F1255-6 has a 6.5 kW immersion heater whilst F1255-12 and F1255-16 have an integrated electric heater of 7 kW with seven steps that automatically engage as necessary. Switchable to four steps of 9 kW. F1255 consists of a heat pump, water heater, electrical module, circulation pumps and a control system. F1255 is connected to the brine and heating medium circuits. F1255 is constructed on a robust frame with durable panels and effective soundproofing for the best possible comfort. All panels are...

Good to know about F1255 Transport and storage F1255 should be transported and stored vertically in a dry place. When being moved into a building, F1255 may be leant back 45 °. The product can be tail heavy. Remove the outer panels in order to protect them when moving in confined spaces inside buildings. 0 EXTRACTING THE COOLING MODULE To simplify transport and service, the heat pump can be separated by pulling the cooling module out from the cabinet. See section "Service" in the installer manual for comprehensive instructions about the separation.

Supplied components Local differences in the enclosed kit may occur. See relevant installer manual for more information. • Position F1255 on a fixed foundation that can take the weight of the heat pump. • Because water comes from F1255, the area where the heating pump is located must be equipped with floor drainage. • Install with its back to an outside wall, ideally in a room where noise does not matter, in order to eliminate noise problems. If this is not possible, avoid placing it against a wall behind a bedroom or other room where noise may be a problem. • Wherever the unit is located, walls...

Installation Inspection of the installation Current regulations require the heating installation to be inspected before it is commissioned. The inspection must be carried out by a suitably qualified person. Pipe installation Pipe installation must be carried out in accordance with current norms and directives. F1255 can operate with a return temperature of up to 58 °C and an outgoing temperature from the heat pump of 70 (65 °C with only the compressor). F1255 is not equipped with external shut off valves; these must be installed to facilitate any future servicing. PIPE CONNECTION BRINE • Insulate...

Guideline values for collectors The length of the collector hose varies depending on the rock/soil conditions, climate zone and on the climate system (radiators or underfloor heating) and the heating requirement of the building Each installation must be sized individually. Max length per coil for the collector should not exceed 400 m. In those cases where it is necessary to have several collectors, these should be connected in parallel with the possibility for adjusting the flow of the relevant coil. For surface soil heat, the hose should be buried at a depth determined by local conditions and...

Functions Control, general The indoor temperature depends on several different factors. Sunlight and heat emissions from people and household machines are normally sufficient to keep the house warm during the warmer parts of the year. When it gets colder outside, the climate system must be started. The colder it is outside, the warmer radiators and under floor heating system must be. The heat pump is controlled by built-in supply and return brine temperature sensors (collector). Brine return temperatures can, if necessary, be limited to a minimum e.g. for ground water systems. Control of the...
