If the TOTEM® is installed in pre-existing heating systems that may be subject to
deterioration, including corrosion, algae formation, limescale build-up, or dirt
deposits, the user system should be preemptively flushed with appropriate products
depending on the problem identified. In some specific cases, a suitable hydraulic
separation device (exchanger) shall have to be installed to protect the TOTEM® ‘s
internal circuit from possible damages and avoid treating the preexisting systems too
aggressively.

Emergency Stop and Shutdown
The TOTEM® can be switched off manually by the User from the Control
switchboard or following the reaching of the pre-set supply temperature, or even
following activation of an alarm signal.
The Arya PLC developed by Totem Energy monitors a set of parameters for engine
functioning and it governs the unit’s shutdown in case a value exceeding the
manufacturer’s preset range is detected.
In addition to being governed by the PLC, the TOTEM® shutdown can also follow
actuation of the emergency relay. Namely, the safety line can be activated in the
presence of the following potentially dangerous malfunctions:
Push the Emergency button
High temperature within the unit’s enclosure detected by the
temperature limiter
Methane detected by the unit’s on-board sensor
H.
Calendar
Through the Calendar function, it is possible to program the Unit to start on set days
and time ranges.
With the Calendar function disabled, the unit will only start following manual input by
the operator from the operator panel.
With the Calendar function enabled, the unit will only be switched on on the days
and time ranges set by the User.
I.
Diagnostics
If the machine is shut down following a command by the PLC, an alarm signal is
displayed on the control switchboard.
The alarm signal can be reset to enable unit’s restart. If the alarm stays on, the unit
won’t start. If that occurs, call the Technical Support Service.
If the unit was switched off due to activation of the safety devices, alongside the
alarm the emergency relay reset button will also light up.
To restart the unit, press the emergency relay manual reset button and reset all
alarms on the Control switchboard.
