OCDS012 1-key basic control
Figure 1.14
OCDS012 1-key basic control
Its functions are:
▶
Light signalling of the presence of errors or warnings.
▶
Error reset.
The OCDS012 1-key basic control does not allow to con-
trol the switching on and off of the appliance for space
heating, nor for the summer ventilation.
Power modulation is managed independently by the gas
unit heater thanks to the presence of the supplied room
probe.
For further details and diagrams see Paragraph
4.4.3
An external request (Paragraph 1.7.9
used to control the operation of the gas unit heater.
1.7.5
OCDS016 2-keys basic control
Figure 1.15

Its functions are:
▶
Light signalling of the presence of errors or warnings.
▶
Error reset.
▶
Selection of the operating mode: heating, summer
ventilation or off.
Power modulation is managed independently by the gas
unit heater thanks to the presence of the supplied room
probe.

OTRG005 thermoregulator

OTRG005 thermoregulator
The thermoregulator is a device that can directly manage
wall-mounted gas unit heaters: the serial interface makes
it possible to create cascade systems managed by a sin-
gle chronothermostat (optional OCDS008, described in
Paragraph 1.7.7
p. 22), with considerable advantages in
terms of thermoregulation, especially in large spaces.
The main functions are:
▶
Turning the gas unit heater on/off.
▶
Ambient temperature measurement by NTC probe.
▶
Automatic management of power modulation.
▶
Diagnostics.
▶
Reset of the flame lockout.
▶
Gas unit heater data display and parameters setting.
▶
Space heating and summer ventilation setpoint set-
ting.
▶
Summer ventilation mode activation.
▶
Possibility of creating cascaded systems.
▶
Modbus interfacing for remote control.

ulator instruction sheet and Paragraph 4.4.5

OCDS008 digital chronothermostat
Figure 1.17
OCDS008 digital chronothermostat
OCDS008 digital chronothermostat integrates the func-
tions of room temperature control and remote control of
the gas unit heaters heating system in a single interface,
specifically designed to make all functions available to the
user in a clear and intuitive way.
It may be used only in association with the OTRG005
thermoregulator.
The main functions are:
▶
Gas unit heaters cascade system management (up to
10).
▶
Hourly programming on a weekly basis on 3 temper-
ature levels.
