DEMAND LIMIT
The microprocessor offers the possibility of limiting the capacity to be delivered to the system for the purpose of limiting the power
input of the unit.
This function is very useful in installations where there are power supply problems.
The limiting applied depends on a 0-10Vdc signal provided by the customer. The number of compressors available to the unit to
satisfy the demand is determined based on this signal. The higher the value of the signal, the less capacity will be available to the
system, as shown in the graphs.
NOTE: when there is a variation in the 0-10Vdc signal, to prevent unwanted and continuous changes in the number of resources
available to the thermoregulator, a delay time is counted in which the signal must remain stable above the step activation or
deactivation threshold, before modifying the percentage of capacity available to the system. This function must be enabled by an
authorised Clivet service centre or by Clivet directly.

ANTIFREEZE THERMOREGULATOR
The function of the antifreeze thermoregulator is to prevent frosting on the exchanger and control, if necessary, the antifreeze heaters.
The thermoregulator has a set point value that determines the activation of the antifreeze alarm, in which condition the compressor
stops, while the pump continues to operate. The ANTIFREEZE SET POINT can be modified only when non-freezing solutions are
used.
The antifreeze thermoregulator is active even when the unit is switched OFF from the panel or the remote contact.
