1.- GENERAL CHARACTERISTICS
1.10.- OPTIONS
COMPRESSOR NOISE INSULATION JACKET
Each compressor is fitted with a compressor acoustic jacket this provides attenuation of the compressor noise that radiates from
the unit when in operation.
SOFT STARTER (for 3N~400V units only)
It is an electronic element, which reduces the peak compressor starting current up to 40%.
INLET PLENUM (models from 0251 to 1303 only)
It is a accessory for adapting the condenser air intake to accept a duct.
SQUARE DISCHARGE DUCT (FP1 and FP2 unit versions and models from 0251 to 1303 only)
It is formed by 1 or 2 square frames, for adapting discharge air from the unit to a square duct.

LOW WATER TEMPERATURE
Necessary for water outlet temperatures below +5ºC
There are three different kits, which depend for selecting on the water outlet temperature desired, as the following table shows:
KIT LOW WATER TEMPERATURE 0ºC
KIT LOW WATER TEMPERATURE -5ºC
KIT LOW WATER TEMPERATURE -10ºC
WATER PUMP (included on Hydraulic and Hydronic versions).
TWIN PUMPS KIT (models from 0251 to 1303 only)
It is formed by two-water pumps mounted in parallel and with same characteristics as a single pump. Only one pump is working,
the other remains on stand by.
When the water pump which is operating cuts out, and the pump turns off, automatically starting the water pump on stand by.
It is possible to select which one of the pumps we want to be working through an external switch supplied with the kit.
With the twin pumps, the available static pressure will decrease 5% from the available static pressure with one water pump only.
TANK ANTI-FREEZE HEATER AND WATER TANK ELECTRICAL HEATER (available only for Hydronic version): an immersion
heater can be supplied complete with safety thermostat and pressure switch fitted in the buffer tank, or an anti-freeze and
supplementary heater (heat pump units only).
Tank anti-freeze heater: It starts when water temperature in the buffer tank is lower than +5ºC (Not for units with low water
temperature kit).
Water tank electrical heater: heat pump units only. The heater works as anti-freeze heater as explained before and as supplementary
heater, when inlet warm water reaches a temperature below a value selected (example: 30ºC) through an independent thermostat
included.

BMS (Interface Mod-bus KP06+Bus Adapter)
It is possible to connect several units with a communication system (MOD BUS Protocol).
ALARM RELAY
It is a free voltage contact which indicates a general alarm in the unit.
DYNAMIC SET POINT (Not available for units EAC 0472 to 0812).
It changes cooling and heating set point according ambient temperature (an extra sensor must be installed).
