6.2 Electrical connections
Connections must be made in accordance with the local standards in force. The equipment’s electric circuit is designed to work with a
single-phase supply voltage of 230 Volts and a frequency of 50 Hz.
The equipment is connected by means of the power cable D (Fig. 2) which comes out of an opening at the bottom of the upright.
The cable must have the features of type H05 RNF or better, and must feature an efficient earth wire of an appropriate size for the total
power of this unit and any other units or accessories connected on the same terminal board (see rating plate).
The unit’s electrical supply system must feature an appropriately sized automatic omnipolar circuit breaker upstream that assures a gap
between the contacts of at least 3mm. There must not be any breaks in the earth cable.
The electrical safety of this equipment is only assured when the above-mentioned conditions are met.
NOTE: This unit has a “Y” electrical connection and, therefore, if the power cable is every replaced, the work must be
performed by a qualified electrician ONLY.
The manufacturer declines all responsibility in the event these safety standards are not complied with.

probe, defective probe, defective connections; check the condition of the probe and correct connection between instrument and probe.
“AH1” high temperature alarm on display indicates that the reading value is higher then the presetted max. value; it causes no effect to
the regulation, the alarm stops when the temperature decreases under the presetted max. value.
“AL1” low temperature alarm on display indicates that the reading value is lower then the presetted minimum value, it causes no effect
to the regulation, the alarm stops when the temperatures rises over the presetted minimum value.
The editing of the thermostat’s CONFIGURATION PARAMETERS, which are factory set, must be performed by qualified personnel only
