The thermostat can be deliverd for wall mounting or panel mounting.
Besides the controlling of the cooling, also the fan and defrost are controlled by the FC 785-PC. Defrost can be a natural defrost, electric defrost or hot-gas defrost.
The thermostats can be connected in a network. When hot-gas defrost is selected, the defrost will first start when one of the other rooms is cooling. When none of the thermostats are cooling the defrost will wait. If this takes too much time, one of the other thermostats will be start the cooling to make hot-gas.
The thermostat has two operation modes. In the cool down phase the cooling is started on request. This means that the cooling will start as soon as the room temperature is too high. In the storing phase the cooling is on relay base. This has the big advantage that only a small refrigeration capacity is required. The relay time is adjustable from 0 till 90 minutes.
The FC 785-PC has a network connection for read-out and data logging on the Alfanet PC software.
