3.3 Basic type C, chilled water treatment
Typical field of use: Demand-dependent of chilled water treatment.

V
Control of chilled water treatment with a RMU7..B as primary controller; chilled
water consumers include the air cooling cool for the ventilation plants or chilled
ceilings with individual room control. The controllers connected via KNX and
exchange the relevant operating data.
Special case: Chilled water and domestic hot water for a 2-pipe system with
heating/cooling changeover. Details described in section 27 "Heating/cooling
cha
ngeover".
Operating mode: Demand-dependent by KNX signal.
The chilled water treatment is switched on and off via the demand signals
(refrigeration distribution zones) for the individual room controllers.
Use of Controller 1: To demand-dependent setpoints by KNX signal.
The flow temperature controller works with a flow setpoint; connected individual
room controllers provide or coordinate the flow setpoints.
 The following aggregates/functions cannot be configured for this basic type:
Fans, heat recovery equipment, mixed air damper, frost protection, preheating
function, sustained mode and night cooling
 Room device QAW740 cannot be used with basic type C
