Temperature control
The controller uses temperature information to manage refrigeration operation according to the configured requirement.
Where it is used. It is used in cold rooms, freezer rooms, chiller rooms and other temperature controlled spaces.
Controller Selection
How a Refrigeration Controller Is Selected
A refrigeration controller should be selected according to the complete refrigeration system rather than as an isolated component. Required temperature, equipment configuration, sensor requirements, operating sequence and room application all influence the controller configuration.
Selected input
Required temperature
The required room temperature determines the control settings and the temperature range that the controller needs to manage.
Affected by this input
Sensor configuration
Sensors are configured according to the temperature monitoring points required for the application.
Selection result
Compressor control sequence
The compressor control sequence is established according to the required temperature and refrigeration system arrangement.
Affected by this input
Defrost configuration
Defrost configuration is established according to the evaporator arrangement and operating conditions of the refrigerated room.

Refrigeration Controller Configuration for Indian Conditions
Indian operating conditions should be considered when configuring controls for a refrigeration system. Ambient changes, frequent door openings, long operating hours, dust, power conditions and product loading are design inputs rather than performance claims.
- High summer temperatures
- Higher outdoor temperatures can affect refrigeration operating conditions, so controller configuration should be coordinated with the selected refrigeration equipment.
- Industrial dust
- Dust around refrigeration equipment can affect connected components, making the site environment relevant to system monitoring and maintenance planning.
- Long operating hours
- Long operating periods require control settings that match the expected refrigeration duty and operating schedule.
- High product loading
- High product loading can create increased cooling demand and should be considered when establishing temperature control requirements.
- Frequent door openings
- Frequent door openings can cause temperature changes inside the room and should be considered when configuring the refrigeration control sequence.
- Power fluctuation considerations
- Power conditions should be considered when planning refrigeration controls and their integration with the connected equipment.
- Seasonal ambient changes
- Seasonal changes can affect refrigeration operating conditions and should be considered when assessing control settings for the system.

Refrigerated room
The room establishes the required temperature and storage conditions that the controller needs to maintain.
Refrigeration Control Upgrades
Upgrade an Existing Refrigeration Controller
An existing refrigeration system may require controller modernization when its current controls no longer match the operating requirements of the room. An assessment can identify whether controller replacement, capacity changes, troubleshooting or a broader retrofit is appropriate.
