Hard Case Tamperproof Electronic Control Devices, Controls by BN Thermic

Hard Case

Energy Saving Tamperproof Electronic Control Devices

• Energy saving control devices because only authorised personnel can adjust temperature settings
• Vandal resistant design suitable for public areas
• Highly accurate electronic temperature control ensures lowest possible heating costs
• Top quality products backed by 5 year warranty

Typical Applications

• Controlling BN Thermic heating systems such as OUH Industrial Unit Heaters and ESP Radiant Cassettes
• Accurate temperature control in shops, warehouses, schools, sports halls etc
• Frequently used as an integral component in a programmable heating system

Features Common to all Models

• Tamperproof design requires a special tool (HC-D) to adjust temperature settings
• Electronic control accurate to within +/- 0.5°C
• Super robust vandal resistant die-cast aluminium enclosure
• Integral black sensor ideally suited for control of radiant heating systems
• Suitable for use with a remote HC-S2 Sensor

HC-T2

Standard Electronic Control Device

Application

Comfort heating control or frost protection

Features specific to HC-T2

HC-ST2

Electronic Control Device with Set-Back

Application

Provides frost protection as a default with a comfort setting for programmable periods

Operation

Operation Mode 1 – Using Integral Run-Down Timer

Ideal for irregularly used facilities

The HC-ST2 has two settings: high (comfort) and low (set-back).  The default setting is low (set-back).  The HC-ST2 incorporates a simple push button which changes the set-point from low (set-back) to high (comfort) for a pre-programmed period between ½ hour and 7½ hours (in ½ hour increments).  Once this period of time has elapsed the device will automatically revert to its low (set-back) setting.

This method of control is ideal for irregularly used facilities such as community halls where the set-back setting will provide frost protection while the hall is unoccupied.

Operation Mode 2 – Using Remote Programmable Timer

Ideal for facilities with a regular pattern of use (with a provision for occasional comfort heating outside normal hours)

The HC-ST2 has two settings: high (comfort) and low (set-back) and requires a remote signal to switch between one and the other.  Typically this signal is provided by a remote mounted 24 hour/7 day programmable timer (TIM-D1) that will ensure that the heating system operates at its low (set-back) setting, providing frost protection while a building is unoccupied (typically at night and at weekends).   The programmable timer has a built-in run-down clock that is triggered by a remote mounted ‘boost button’ (HC-B1).  This feature will provide a temporary temperature boost for a pre-determined length of time during a period when the system would normally be in set-back mode.  The boost command can be cancelled by depressing the ‘boost button’ for 3 seconds.

This system is ideal for premises that have a regular pattern of use but may occasionally be used outside normal hours.

Features specific to HC-ST2

HC-S2 Remote Sensor

Optional remote mounted sensor for use with HC-T2 and HC-ST2 tamperproof electronic control devices.   When the provided gasket is fitted, the unit will conform to IP55 (protected against water sprayed from all directions).  

Dimensions: 74 x 51 x 28

HC-D Special Tool for Removing Tamperproof Screws

The key to the Hard Case energy saving potential is the HC-D. Without this device it is impossible to adjust temperature settings. This ensures that changes are only made by authorised personnel and prevents casual or willful adjustments being made.
