Connect the drain hose with a slope
and a pipe vent to the public sewer.
Note
■ In underfloor heating circuits, install a
temperature limiter as a maximum
temperature limiter for underfloor
heating systems (see page 50).
■ Safeguard minimum flow rate, e.g.
with overflow valve (see Specification
on page 113).
Connecting a cooling circuit if required
Size and provide all components
required for the cooling circuit on site
(including plate heat exchanger).
For area cooling systems (e.g. under-
floor heating circuit, chilled ceiling), pro-
vide an
on-site
contact humidistat.
Requirements of the contact humidistat:
■ Electrical connection: 230 V~, 0.5 A
■ Installation inside the room to be
cooled at the cooling water flow
(remove thermal insulation if neces-
sary).
■ If several rooms with different relative
humidity are part of the cooling circuit,
fit and connect several contact humidi-
stats in series.
Switching contact as N/C contact.
