Hydro tower with external heat pump manager
Compact installation for heating and domestic hot water preparation
HWK 332
The hydro tower enables the fast and simple connection of a heat pump for heating purposes to a heating system with an unmixed
heating circuit.The heat pump manager included in the scope of supply of the heat pump is used for the electronic control of the com-
ponents (external wiring required). The following components are installed in a space-saving way and wired ready for use:
• Switchable pipe heater (2/4/6 kW)
• Buffer tank (100 l) with installation option for an additional immersion heater (up to CTHK 634).
• Hot water cylinder (300 l) with installation option for an additional heating element (flange heater).
• Electronically regulated circulating pump (energy-efficiency class A) pre-wired with coupling relay for an unmixed heating circuit
(consumer circuit).
• Unregulated circulating pump integrated for the generator circuit and hot water circulating pump.
• The hydraulic isolation of the generator circuit and the consumer circuit is done via two differential pressureless manifolds (bypass
pipes), which are each fitted with a check valve.
The unregulated circulating pump in the generator circuit is only operated when the compressor is running in order to reduce the
runtimes.The uniform flow through the buffer tank connected in series extends the runtimes of the compressor and ensures the required
heating water flow in all operating situations.

Low-temperature air-to-water heat pump
for installation close to walls
LA 8AS
Air-to-water heat pumps for outdoor installation with external temperature controlled WPM 2006 plus heat pump manager. The diago-
nal air circuit allows installation close to walls. A minimum clearance of 30 cm must be allowed for on the air intake side. When mounting
is done in an unprotected place, the air outlet must not be positioned against the main wind direction. Sound-optimised through the
use of low-speed crescent wing axial-flow fans. Energy-efficient defrosting by reverse circulation und diagonally positioned evaporator.
Universal design with optional DHW preparation and the option of flexible expansion for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Integrated flow sensor and soft starter, return flow sensor and external temperature sensor included in the scope of supply.
Electric cable EVL . . . to connect the heat pump and heat pump manager, must be ordered separately.

Air-to-water heat pumps for outdoor installation with external temperature controlled WPM 2006 plus heat pump manager. Sound-opti-
mised through the use of low-noise „owl‘s wings“ ventilator blades;Energy-efficient defrosting by reverse circulation. High coefficients of
performance due to compliance with EN 14511 for larger volume flows on the heat consumption side. Observe the minimum clearances
for installation close to walls. Universal design with optional DHW preparation and the option of flexible expansion for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Integrated flow sensor and soft starter, return flow sensor and external temperature sensor included in the scope of supply.
