12.2 - Description
12.2.1 - Hydraulic module without variable speed 
(Options 116R, 116S, 116T, 116U)
The hydraulic module is composed of the system's main hydraulic 
components:  factory-tted  water  pump,  screen  lter  and  relief 
valve. 
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:
 - Option 42A (42B if option 307): hydraulic module protection 
(42A) or hydraulic module and buer tank protection (42B) 
down to an outdoor temperature of -20 °C.
 - Option 293: Expansion tank for water circulation system.
IMPORTANT: The use of the hydraulic module on open 
systems is prohibited.
12.2.2 - Hydraulic module with variable speed 
(Options 116V, 116W)
The composition of the hydraulic module with variable speed is 
similar to that of the hydraulic module without variable speed.
In this case, the pump is controlled by a variable frequency drive 
that allows the pump's nominal ow rate to be adjusted according 
to the chosen  control  mode  (constant  pressure  or temperature 
differential,  or  fixed  speed)  and  the  installation  operating 
conditions.
IMPORTANT: The use of the hydraulic module on open systems 
is prohibited.
