| Usage: | Cascade boiler room |
| Number of controlled boilers: | up to 32 boilers |
For the purpose of communication between different control systems and THERM boilers, we have developed our own cascade controller THERM TKR, which conveniently processes the incoming signal and transmits the information about the desired action to the boiler or cascade of boilers. It is therefore used as an intermediary to facilitate communication between the boiler cascade and the parent control system such as THERM VPT or single zone controller. System parameters are easily set using the touch screen display. As well as passing information to the boiler assembly, it can process and pass fault information back to the parent control system.
We offer the cascade controller in a convenient version of a complete mounting box designed for controlling 1-3 boilers in a cascade. Of course, it is possible to use individual additional modules and extend the controller to control up to 32 boilers. In the case of installing your own switchboard, the recommended kits are provided.

Additional modules
Set TKR MAS/3
| Order No.: | 42717 |
The TKR MAS/3 cascade controller independently controls a cascade of up to 3 boilers. To increase the number of boilers in the cascade (up to 32 boilers), TKR SOT expansion modules are used. On the display of the controller we can set a constant output temperature or an equithermal curve, or we can use a parent controller with OT/+ communication to set the output temperature, or we can control the output temperature with a voltage of 0 – 10 V. Supply voltage 5 V, DIN rail mounting, width 4 modules.
Set TKR MAS/2

The TKR MAS/2 cascade controller independently controls a cascade of up to 2 boilers. To increase the number of boilers in the cascade (up to 32 boilers), TKR SOT expansion modules are used. On the display of the controller we can set a constant output temperature or an equithermal curve, or we can use a parent controller with OT/+ communication to set the output temperature, or we can control the output temperature with a voltage of 0 – 10 V. Supply voltage 5 V, DIN rail mounting, width 4 modules.
Set TKR SOT
| Order No.: | 42718 |
The TKR SOT expansion module is used to connect another boiler to the TKR MAS/2 or TKR MAS/3 controller, it is mounted on a DIN rail, width 1 module, connection with the controller is provided by the TKR BUS mounted in the DIN rail.
Control display for DIN-rail
| Order No.: | 42719 |
The TKR DIS touch screen is used to set additional functions, display the cascade status and parameters of each boiler in the cascade or change the factory setting of the controller parameters. The display has a width of 5 modules, is mounted on the DIN rail to the left of the controller, is permanently connected to the controller, communication and power supply is provided by a connecting cable included in the display. The service technician can use REK GTP-S for service setup.
Power supply 5 V/2,4 А for DIN-rail
