Vitocal 343-G<br />
Vitocal 333-G<br />
The compact heat pumps Vitocal 343-G and<br />
Vitocal 333-G are offered as three versions,<br />
i.e. with and without solar thermal connection<br />
and with integral natural cooling function.<br />
DHW cylinders with 170 litre capacity (solar<br />
version with 220 l) are integrated to safeguard<br />
high DHW convenience. At the core of the<br />
appliance is a newly developed high efficiency<br />
heat pump module.<br />
These compact appliances are highly efficient<br />
thanks to the new refrigerant circuit with<br />
electronic expansion valve (EEV) and the<br />
<strong>Viessmann</strong>-developed RCD (Refrigerant Cycle<br />
Diagnostic) systems plus the standard energysaving<br />
DC pumps. This is reflected day by day<br />
and year by year in high seasonal performance<br />
factors and low consumption costs.<br />

Small footprint<br />
With their space saving designs, the<br />
Vitocal 343-G and Vitocal 333-G are<br />
particularly suitable for anywhere where<br />
space is restricted. The brine and heating<br />
circuit pumps and the 3-way diverter valve are<br />
already integrated inside the compact casing<br />
that completely protects the cooling module/<br />
hydraulic compartment from the outside<br />
environment and, in conjunction with the<br />
new three-dimensional anti-vibration mounts,<br />
minimises operating noise. These compact<br />
heat pumps are some of the quietest in their<br />
category, as they only generate 38 dB(A) at<br />
0/35 °C.<br />
For easier handling, the height of the unit was<br />
reduced and the body designed to split into<br />
sections. Variable connection accessories<br />
supplied ex works make heat pump<br />
installation easier.<br />
Extremely easy to operate<br />
Like all our compact appliances, the<br />
Vitocal 343-G and Vitocal 333-G, too,<br />
are equipped with the new, user-friendly<br />
Vitotronic control unit. If in doubt, help is<br />
available at the push of a button. The graphic<br />
interface will also display heating curves and<br />
solar yield.<br />
The programming unit of the Vitotronic control<br />
unit can be removed from the front of the<br />
appliance and be replaced with an external<br />
programming unit, available as an accessory,<br />
and a dummy cover. A five metre long power<br />
cable enables the external programming<br />
unit to be mounted almost anywhere in a<br />
convenient position on a wall mounting base.<br />
Always accessible<br />
Subject to demand, the new Vitotronic<br />
control unit can be fitted with convenient<br />
communication technology. From<br />
Vitocom 100 to Vitocom 300, versatile remote<br />
monitoring and remote control options are<br />
available wherever you are.
