How it Works

Hard Case is a range of energy saving tamperproof thermostats ideally suited to public areas.  These are the key features of the range.

  • Energy saving because only authorised personnel can adjust temperature set-points
  • Energy saving because highly accurate electronic control means eliminates temperature fluctuations
  • Vandal resistant die-cast aluminium case ideally suited to public areas

HC-T2 Tamperproof electronic thermostat

The basic hard case thermostat is a simple device providing reliable and accurate temperature control.  An HC-D tool is required to remove the lid allowing the user to select temperature range (comfort or frost protection), temperature set-point and differential.

HC-ST2 Tamperproof thermostat with set-back and run-down timer

The HC-ST2 is a more sophisticated device providing a low temperature setting (set-back) as a default and a higher temperature setting (comfort) for programmable periods.

There are two methods of selecting the comfort setting:

Operation Mode One – Using Integral Run-Down Timer

The HC-ST2 incorporates a side-mounted push button.  Once the button is pushed the temperature set-point will change from low (set-back) to higher (comfort) for a pre-programmed period (between ½ hour and 7 ½ hours).  Once this time period has elapsed, control will automatically revert to the low (set-back) setting. 

The two temperature settings as well as the run-down timer setting are all easily adjustable using the knobs and switches under the tamperproof lid.

Operation Mode Two – Using Remote Programmable Timer

The temperature set-point of the HC-ST2 changes from low (set-back) to high (comfort) according signals received from a remote programmable timer (model TIM-D1).

The TIM-D1 timer can be connected to a push button (TIM-B1) which will provide temporary boost to the higher (comfort) setting when the system would normally be in set-back mode.  The duration of the boost is set on the TIM-D1 timer and the boost signal can be cancelled by pressing the TIM-B1 button for 3 seconds.
