(e .g . for floor heating, cooling)
Inputs and outputs (external interfaces)
Comments
Use additional circuit board CZ-NS1P, CZ-NS2P
or CZ-NS3P
Connect the 3-way directional valve
so that it prevents flow through the
solar circuit and heat exchanger of
the hot-water tank when closed .
These two terminals are jumpered
on delivery . Connection:
1-pin (min . 3 mm contact clearance)
When the contacts are open, the device is switched
off and the remote control is disabled .
The jumper between terminal 17 and 18 must be
removed, if the external control device (optional) is
connected to the hydro module . The max . operating
current of the control device must be less than 3 A
Use an NTC sensor
Terminals 13 / 14 must be jumpered if no temperature
limit switch is used for the hot-water tank
For exclusive control of heating
mode via the external room thermo-
stat, only phases L and L1 are con-
nected to the terminal strip .
This also applies for devices without a cooling
function . This connections do not permit switching
between heating and cooling mode .
