20.4 ALUMINIUM CASING - CVCAL<br />
With this option, casing of the unit is made of aluminium instead of standard steel zinc<br />
plated sheet. As standard, aluminium casing is not painted.<br />
20.5 HIGH/LOW TEMPERATURE ALARM THERMOSTAT - TMC/TMF<br />
TMC (option for high temperature signal) and TMF (option for low temperature signal) are<br />
mechanical wall-mounted thermostats. They consist of thermostats with bi-metallic sensor<br />
element for switching signal transmitters. Their adjustable range is from 0°C to 60°C, contacts<br />
6A-250VAC. Type of contacts NC for TMC and NO for TMF.<br />
20.6 RELAY FOR POTENTIAL FREE COMMON ALARM SIGNAL (HIGH AND LOW<br />
PRESSURE, HIGH TEMPERATURE) - CA<br />
HP (high pressure alarm), LP (low pressure alarm) are not available as separate signals.<br />
CA, common alarm, is the consequence of the following alarms (high pressure+low<br />
pressure+high temperature). When one of these three symptoms appears, common alarm<br />
is activated to warn about possible faults on the unit.<br />
20.7 <strong>AIR</strong>FLOW SIGNAL - FL<br />
It consists of a differential air pressure switch. It provides a voltage-free signal by a N.O.<br />
contact when air flow pressure is different from the rated value, to indicate a fan malfunction.<br />
This value of intervention is factory pre-set according to the unit model.<br />
