KT-2A • Regulations/Thermostats

  • Geothermal heat pump
  • KRONOTERM
  • Controller/Thermostat
  • MANDATORY OPTION FOR ETERA

The KT-2A controller from KRONOTERM is a multifunctional thermostat and regulation that works perfectly with the ETERA heat pump. At least one KT-2A must be provided in every installation in which a KRONOTERM heat pump is used.

Brand

  • KRONOTERM

Application

In combination with the ETERA heat pump:

  1. Temperature control per zone (room heating/cooling):
    • In combination with the ETERA you can control up to 2 or up to 4 (if KSM+ 2) heating loops.
    • Adjustable in modes such as NORMAL, ECO and COMFORT.
2. Sanitary hot water management (DHW):
    • Setting the desired temperature.
    • Activation of one-time fast heating.
    • Manual anti-legionella program.
3. Control of additional heat sources:
    • Control of an internal (electric) and external (e.g. gas/fuel oil) additional heating element.
4. Control of the heat pump itself:
    • Switching the ETERA heat pump on and off.
    • Switching between heating, cooling and standby mode.
5. Use of schedules:
    • Set daily or weekly schedules for comfort settings per zone, hot water, pool, etc.
6. Control of buffer tanks and pool heating:
    • With customized temperatures and schedules.
7. Access to data and error messages:
    • Insight into system status, temperatures, pressure, alarms and energy consumption.
8. Cloud connectivity:
    • Remote access and control via the Cloud.Kronoterm.com platform.

The KT-2A is suitable for simple thermostat functions as well as for advanced system control of the entire heat pump installation.
