 HP with acoustic optimisation
P21 = 2 with acoustic optimisation
Default value of P181:
5 to 13 bar (resolution: 0.1) if P1=R134a, Default value: 8
Default value of P182: 25°C
Standard control applies to the other parameters.
1 V-frame condenser fan module per circuit = 1 stage (1 fan) with speed control + 1 single-speed stage (same as standard)
2 V-frame condenser fan modules per circuit = 1 stage (2 fans) with speed control + 2 single-speed stages (same as standard)
3 V-frame condenser fan modules per circuit = 1 stage (3 fans) with speed control + 3 single-speed stages (same as standard)
4 V-frame condenser fan modules per circuit = 1 stage (4 fans) with speed control + 3 single-speed stages (same as standard)
 HP with energy optimisation
P21 = 3 With energy optimisation (available only with an electronic expansion valve)
If 4 stages: 10-25-40% and 60-75-90% for stages 2-3-4
If 3 stages: 15-30% and 70-85% for stages 2-3
If 2 stages: 20 and 80% for stage 2
The settings of parameters P181, P182, P185, P187 and P189 must be reset.
P181 = 6.8 b
P185 = 3.8 b
P182 = 30°C
In this case, parameters P181, P185, P187 and P189 can be adjusted in increments of 0.1.
Parameters P186, P188 and P190 are not necessary and therefore made inaccessible.
