    INTRODUCTION The model Hydrosplit-M3 is a separate electronic calculator that measures the thermal energy used in the heating and cooling systems. The calculator allows the simultaneous calculation of: - Thermal energy in a heating/cooling system. - Volume up to 2 flow meters for hot and cold sanitary water. The calculator is equipped with two pulse emitter outputs (one for the heating data and one for the cooling data) and one output for the Wired M-Bus network link.

  • Page 3: Installation

    INSTALLATION CALCULATION UNIT Open the calculation unit by leveraging on the four hooks on the sides [1] and remove the cover [2]. Remove the bracket behind of the calculation unit and secure it to the wall. There are two types of wall mounting allowed: direct wall mounting by using the mounting bracket and the following hooking of the calculation unit on the same bracket;...

    Then apply the basis on the bracket and secure it with any anti-removal seals. After the installation, connection, configuration and commissioning, close the cover and apply adhesives and / or lead sealings. TEMPERATURE SENSORS INSTALLATION For the temperature sensors installation, see related manual. FLOW METERS INSTALLATION For the flow meters installation, see related manual.

    VOLUME METERS C1/C2IN CONNECTION The inputs C1 IN (51, 52, 53) and C2 IN (54, 55, 56) are dedicated to the flowmeters for hot and cold sanitary water. The calculation unit is compatible with flowmeters with pulse output OC (open collector) or OA (reed), with pulse value “liters/pulse”...
  • Page 8 M-BUS NETWORK CONNECTION The inputs/outputs “M-Bus” (24 and 25) are dedicated to the calculator connection with an M-Bus network cable. For the connection is not necessary to respect the polarity, although it is advisable to keep the same polarity on the entire cable network. Warning: the M-Bus network is using voltage that can damage the device when applied to terminals dedicated to other functions, so be careful when connecting to this interface.
  • Page 9 AUX POWER SUPPLY CONNECTION The terminals 59 and 60 (Aux Power) are dedicated to the connection of the calculation unit to an external electric network by using a power adapter (3.6 ÷ 5 VDC, 300 mA) provided as an accessory. When connected to the power supply, the battery will be used as backup power source.

  • Page 10: Communication Interfaces

    COMMUNICATION INTERFACES HEATING/COOLING PULSE OUTPUT INTERFACE The pulse outputs (Open Collector – max. 30V, 50mA), when connected to suitable totalizers compatible, allow the remote reading of heating and refrigeration units consumption. The calculation unit is equipped with a pulse output dedicated for heating units (16, 17) and one dedicated to the refrigeration units (57, 58).
