11. ANTI-FROST MANAGEMENT
Termo-Reg unit has a function preventing ice formation in the recovery unit which is activated when
the temperature of exhaust air drops down to 1ºC, in which case the procedure is as follows:
• First, open the By-pass to prevent condensation in the recovery unit, thereby preventing the forma-
tion of frost.
• The equipment continue to run for several minutes to be monitored continuosly the exhaust air
temperature. If this does not rise by 1ºC, the equipment will stop.
• After 15 minutes stopped, the equipment will automatically start up, cyclically repeating the above
steps.
12. ALARMS
When an error occurs, the Termo-Reg unit informs to the user with the status LED control terminal
equipment and by activating an available digital contact available in the electrical panel (Poten-
tial free). This LED fl ashes regularly during normal operation.
To know the error that is produced it is necessary to observe the LED the remote terminal status. In
case of failure, it emits a certain number of fl ashes depending on the error, as shown in the following
table:
