Mains Operated Version Of TP5000 Si Introduced
|
|
Danfoss Randall has introduced a mains-operated (230V, 50Hz) version of its hugely popular and versatile TP5000 Si programmable room thermostat.
Incorporating all the outstanding features of its predecessors, this new TP5000M Si removes the need to periodically replace and dispose of dry-cell batteries, making it a slightly ‘greener’ solution. It is ideal for new-build properties with ready-installed power supplies or for replacing existing ‘accelerator-type’ room thermostats where supply cables are already in place. |

The TP5000M Si is a simple-to-install-and-use 5-day/2-day programmable room thermostat that can be configured by the installer to provide 2, 4 or 6 events per day - or constant temperature control when required.
A big plus is the unit’s factory-set real-time clock with calendar function that eliminates any time-setting and BST/GMT time changes. Users do not have to alter the clock twice a year and installers need not set the time after unpacking the unit.
Chrono-proportional control modeis standard for the TP5000M Si. This fast-reacting, energy-saving control mode varies boiler on/off percentages to satisfy comfort requirements. Chrono-proportional cycling rates of 3, 6, 9 or 12 per hour can be selected. Conventional On/Off control mode is selectable by the installer.
The optional Service Interval function helps landlords comply with the annual boiler servicing requirements of Gas Safety Regulation 36. With this function operating, the unit provides audible and visual warnings from 28 days before servicing is due then reduces the heating output should the due date pass. More socially acceptable than switching off the heating altogether, this encourages tenants to allow access for servicing.
Other features of the TP5000M Si include:
-Large, easy-to-read LCD display.
-Built-in switching programme, easily changed by user to suit individual requirements.
- Programmable remote sensor inputs including remote room sensing, limit sensing for floor heating applications and tele-switch or window switch sensing.
- Selectable operating modes 5/2 day, 24 hour or A/B block programming.
- Selectable 6, 4 or 2 events per day.
- Fixed time, Delayed Start or Optimum Start start-up options.
- All user settings, including overrides, stored in non-volatile memory independent of battery state.
- Thermostat mode and frost protection.
Additionally, there are numerous simple push-button overrides that enable users to cope with temporarily changing heating needs. |
