DeSCRIPTION
The OTRG005 thermoregulator is a device that can direct-
ly manage Robur gas unit heaters: the simple and intuitive
display interface allows the user to change the control pa-
rameters, switch the unit on/off and change the operat-
ing mode; a serial interface also allows to create cascading
systems managed by a single chronothermostat (optional
OCDS008), with considerable advantages in terms of tem-
perature control, especially when installing gas unit heat-
ers in large spaces.

PROCEDURE
REFERENCE (to other document)
The design, installation, operation and maintenance of
the systems shall be carried out in compliance with cur-
rent applicable regulations, depending on the Country
and location, and in accordance with the manufacturer's
instructions. In particular, regulations regarding the fol-
lowing shall be complied with:
Electrical systems and equipment.
Fire safety and prevention.
Any other applicable law, standard and regulation.
Any contractual or extra-contractual liability of the
manufacturer for any damage caused by incorrect

This operation must be curried in total safety.
Before starting intercept the gas and disconnect
the power supply.
When using the OTRG005 thermoregulator in com-
bination with Next-G series gas unit heaters, the gas
unit heater will be managed by the thermoregulator
on two power levels using the temperature probe
connected to the thermoregulator, instead of
using continuous heat output modulation.
