Page 3: Safety Instructions
SATK22 Safety Instructions Key to Symbols In the case of particularly hard or impure water, there must be suitable provision for filtering and treating the water Primary circuit flow before it enters the device, in accordance with current legislation. Failure to do so may result in the HIU becoming damaged or working incorrectly. -

Page 7: Installation
SATK22 Installation The SATK22 HIU is designed for installation in a sheltered domestic environment (or similar), therefore it cannot be installed or used outdoors, i.e. in areas directly exposed to the weather. Outdoor installation may cause malfunctioning and hazards. If the appliance is enclosed inside or between cabinets, sufficient space must be provided for routine maintenance procedures. It is recommended to place electrical devices underneath the HIU, as they may become damaged in the event of leaks occurring at the hydraulic fittings. - Page 8 SATK22 Installation with mounting bracket Connections at the bottom Connections at the top Installation with mounting bracket and first fix bracket Ensure the wall is structurally suitable for mounting the HIU, follow this instruction below. • Using the mounting bracket as a template mark the position of the holes required to secure the HIU to the wall. Ensure the mounting bracket is horizontal.

SATK22 Connections at the top NOTE: When installing with the connections at the bottom secure with safety screws as shown. Install the SATK22 as shown and using sealing washers connect the HIU to the valves on the first fix bracket. Hydraulic connections Based on the dimensions and connection diagram on page 3. -
Page 10: Electrical Connections
SATK22 Electrical Installation Continued Connecting to the electricity supply To extend the cable if necessary, use a flexible cable suitable for kitchen and heating appliances and for home, kitchen and office installations, also in humid environments subject to medium levels of mechanical stress (e.g. H05V2V2-F: Uo/U 300/500 V). -

Page 14: Heating Functions
SATK22 Heating Function Heating flow temperature setting (SATK2210. and SATK2220.) To set the flow temperature press the <SET> key until the symbol in the red circle appears. Use the <R> knob to change the value. The flow temperature range is: 25–45˚C for SATK2210. - Page 15 SATK22 Heating Function OPTIONAL SETTING: modulating temperature regulation with compensated set point (technical parameter t01= 2) (SATK2210 & SATK2220) When the function is enabled, the flow temperature is modified (±10°C with respect to the set point for HIU in HIGH temperature, ±3°C if in LOW temperature) according to the temperature detected by the return probe in order to maintain this latter temperature value constant.

Page 16: Dhw Functions
SATK22 DHW Function The DHW cycle always takes priority over the heating cycle. DEFAULT SETTING: fixed DHW set point (parameter t06=0) When DHW cycle activation is requested, due to DHW tapping by the user (detected by the domestic water flow meter), the regulator modulates the valve opening in order to adjust the temperature detected by the domestic water probe to the selected set point value. - Page 17 SATK22 DHW Comfort Function - Pre-heat, DHW Re-circulation The comfort function can be, alternatively, preheating of the DHW plate heat exchanger or management of DHW recirculation. They are enabled by setting to ON or PROG the comfort function (see page 12). DEFAULT SETTING: DHW exchanger preheating function (parameter t02 = 0) During periods when the domestic water...

Page 21: Modbus
SATK22 Modbus The HIU offers a remote connectivity solution by means an RS-485 wired network and Mod-Bus communication protocol. On request, Altecnic will supply a map of the Mod-Bus registers and data transmission specifications so the product can be integrated in an existing BMS system. The RS-485 communication network should be preferably constructed in compliance with the prescriptions of standard RS-485. -
