Heat pump for heating purposes for outdoor installation with wall-mounted WPM EconPlus heat pump manager. Sound-optimised
through the use of slow-running „owl‘s wing“ fans with a low, natural-sounding noise, an encapsulated compressor housing with free-
swinging compressor baseplate for solid-borne sound insulation. High COPs through high-performance evaporator and compliance
with the requirements of EN 14511 for larger volume flows on the heat consumption side. Sensor monitoring of the refrigerating circuit
for energy-efficient defrosting; integrated thermal energy metering (display of the thermal energy volume for heating and domestic hot
water preparation on the WPM EconPlus heat pump manager). Access for servicing on the outlet side; observe the minimum clearances
for installation close to walls. Universal design with the option of flexible expansion for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Integrated soft starter, flow and return-flow sensors; external sensor (standard NTC-2) included in the scope of supply.
Electrical connection cable EVL . . U between heat pump and heat pump manager must be ordered separately.

Heat output and COP according to EN 255 (EN 14511) at A2/W35 (A2 = air intake temperature +2 °C, W35 = heating water outlet temperature +35 °C)
The air outlet must be positioned at a right angle to the main wind direction if unsheltered outdoor installation is carried out. If this is not possible,
a weather protection hood must be installed!

LA 40TU
Heat pump for heating purposes for outdoor installation, with wall-mounted WPM EconPlus heat pump manager and two compressors
for output reduction when operating at partial load. Sound-optimised through the use of slow-running „owl‘s wing“ fans with a low,
natural-sounding noise, an encapsulated compressor housing with free-swinging compressor baseplate for solid-borne sound insulati-
on. High COPs through high-performance evaporator and compliance with the requirements of EN 14511 for larger volume flows on the
heat consumption side. Sensor monitoring of the refrigerating circuit for energy-efficient defrosting; integrated thermal energy metering
(display of the thermal energy volume for heating and domestic hot water preparation on the WPM EconPlus heat pump manager). Ac-
cess for servicing on the outlet side; observe the minimum clearances for installation close to walls. Universal design with two compres-
sors for modulating operation, optional DHW preparation and the possibility of flexible expansion for:
• Bivalent or bivalent-renewable operating mode
• Distribution systems with unmixed and mixed heating circuits
Integrated soft starter, flow and return-flow sensors; external sensor (standard NTC-2) included in the scope of supply.
