12.2.1 - Touch Pilot Control (option 158)
The interface of the "Touch Pilot Control" has the following
characteristics:
• It is a colour interface.
• It is intuitive and user-friendly. Clear and concise
information is presented in the local language (8 available).
• The complete menu can be adapted to the various users
(end customer, maintenance personnel, manufacturer),
• Unit use and conguration are secure. Password protection
prevents non-authorized access to advanced settings.
• No password is required to access the most important
operating parameters.
12.2.2 - Hydronic module without variable speed
(options 116R, 116S, 116T, 116U)
The hydronic module is composed of the system's main
hydronic components: factory-tted screen lter, relief valve
and water pump.
The xed speed operating pressure pump provides the nominal
ow rate for the system water loop.
Several types of water pump are available to suit all applications:
• Single or dual low pressure pumps
• Single or dual high pressure pumps.
The nominal ow rate of the system should be adjusted using
a manual control valve provided by the customer.
The relief valve placed on the water inlet pipes at the pump
inlet limits the pressure to 400 kPa (4 bar).
A screen lter that can be easily removed is placed at the pump
inlet and protects the pump and the plate heat exchanger against
solid particles that are greater than 1.2 mm.
Additional options can be ordered if necessary:
• Protection of the hydronic module in outdoor temperatures
of down to -20°C.
• Expansion vessel.
The use of the hydronic module on open systems is
prohibited.
12.2.3 - Hydronic module with variable speed
(Options 116V, 116W)
The composition of the hydronic module with variable speed
is similar to that of the hydronic module without variable
speed.
In this case, the pump is controlled by a variable frequency
drive that allows adjustment of the pump's nominal ow rate
according to the chosen control mode (constant pressure or
temperature differential or fixed speed) and the system
operating conditions.
The use of the hydronic module on open systems is
prohibited.
12.2.4 - Partial heat recovery (Option 49)
This option enables free hot water to be produced through
heat recovery by desuperheating the compressor outlet gas.
The option is available across the entire range.
A water-cooled heat exchanger is installed as standard with
air-cooled exchangers on the compressor discharge line on
each circuit.
The control is congured for the partial heat recovery option
in the factory (see the section on Control conguration with
the desuperheater option).
The installer must protect the water type heat exchanger
against the risk of frost.
