Frost Protection
Strategies involve modulating heat exchanger speed or using electrical pre-heating to prevent freezing.

Time Schedule and Commissioning
Controller allows configuration of up to six time slots for operation modes. Commissioning can be performed using the TACtouch touchscreen interface or a basic position switch.

Specifications
The touchscreen controller has a 1.5-meter cable for connection to the control circuit board, with specifications including an operating temperature range of 0 to +50°C and protection class IP20.

Image Management
The basic setup menu activates automatically on startup. The main menu is accessible via a rotary menu, displaying key data such as current operation mode, date and time, and active alarms.

Control and Settings
The control menu allows users to change basic parameters and operation status, including switching the unit on/off and adjusting setpoints.

Alarm and Maintenance
Alarms are displayed on the main screen, and active alarms can be viewed and reset. Maintenance settings include configuring service-related settings and setting maintenance warning intervals.

Basic Setup
Guides users through critical settings such as language, units, airflow regulation, temperature, and fire alarm settings.

Advanced Setup
Requires a code and special training, including settings for stopping fans with 0-10V signals and pressure control.

Boost Mode

Post Ventilation
Automatically activates when an electrical heating coil is used, keeping fans running for a specified time.

Internal and External Coils
Preheating coils prevent moisture and frost issues. External coils require on-site installation and configuration.

Frost Protection
Anti-frost sensors protect water coils from freezing, activating alarms and opening valves if temperatures drop below 4°C.

Freecooling
Configurable based on outdoor and room temperatures, with a factory setting of 0°C for outdoor and 22°C for room temperature.

Modbus and LAN Configuration
Requires additional hardware for communication. Factory settings include an address of 1 and a baud rate of 9600.

0-10V Output
Configurable outputs for airflow or pressure, with factory settings for specific fan outputs.

Maintenance
Regular maintenance is crucial for optimal operation, including filter replacement and component inspection every 3 to 12 months.

Troubleshooting
The TAC5 control board manages alarms, categorized into auto-resetting and non-auto-resetting types.

Alarm Types and Descriptions
Includes various alarm types such as pressure variation, reference pressure initialization, setpoint fulfillment, data failure, fire alarm, maintenance alarm, communication breakdown, and temperature sensor failures.

Key Procedures and Recommendations
Ensure proper configuration of fire alarm inputs and advanced setup options. Regular maintenance and monitoring of fan operating hours are crucial.

Overview
Provides technical specifications, procedures, and maintenance instructions for a system involving bypass actuators, control boards, and heat exchangers.

Specifications and Procedures
Replacement of damaged position sensors on bypass actuators is necessary. Alarm types include incorrect position of the modulating bypass and maintenance hours limit for filters.

Key Parameters and Commissioning
