 |
| Application |
These controllers are specifically designed for freezers, cold rooms & refrigerated trucks. |
| |
| Installation |
Controllers are panel mounted. For SZ-7523-P,SZ-7524-P to have an IP65 degree of protection ,silicon sealant should be applied around the perimeter of the panel cutout before they are secured.
The temperature range allowed for correct operation is 5 to 50 deg. C .Avoid places subject to strong vibrations, corrosive gases, excessive dirt or humidity. The same recommendations apply to probes. Let air circulate through the vents provided. |

| Function |
They are suitable for use with refrigerating units and control the cooling cycle (COMP relay output),evaporator ventilator operation (Evap. Fan relay output) and defrost cycles via resistances or by inverting the gas cycle(Heater relayoutput).The CRC-1100 has an additional relay for alarm signaling.
They are also provided with two NTC probe inputs, one for temperature control, the other, to be located onto the evaporator, to control the defrost termination temperature and to managed the fan.
The CRC-1100 and SZ-7523-P have a digital Input for High/Low Pressure. In addition to this, the CRC-1100 has an LCD read out and the SZ-7523-P has a 20A power relay output for compressor. |
