INFO
- Connection is made with a shielded wire (shielded four-wire cable (two twisted
pairs) J-Y (ST) Y 2x2x0.8) to the communication line (12 V, A, B, GND (31 - 34)).
ANF(H)2 – switching contact - allows simple control of the heating circuit in ON / OFF mode.
ANFHa (b) – switching contact (for terminals - DVI1, DVI2) - allows easy control of the
heating circuit by classic room thermostat (230 V / 50 Hz) in
ON
mode (e.g. Comfort /
OFF (switched off).
ANFa (b, c, d, e) – switching contact (for terminals - VI1, VI2, VI3, VI4, VI5) - allows
easy control of the heating circuit by any device (potential-free thermostat) in ON mode -
switched terminals (e.g. Comfort /
OFF
- disconnected terminals (switched off).
MDM(H)1 – remote working mode switching by “modem” - enables simple control of the
heating circuit in ON / OFF mode.
MDMHa (b) – remote working mode switching using modem - 2
nd
status logic for
switching operating modes remotely using an external device (230V) that changes the status
at the selected input (DVI1, DVI2):
Input disconnected = AUTO status - status when it is possible to manually
switch between operating modes or let the controller run according to the time
programs.
Input short-circuited = STBY status - status when the STBY working mode
is forced, when the heating circuit is heating to the room temperature defined
by → P08
Heating circuit
parameter and circuit for DHW is heating to a constant
temperature = 5 °C.
