SALUS HTRP230 vs HTRS230 – Model Overview and Key Differences
The SALUS HTRP230 and HTRS230 are wired
electronic room thermostats designed for underfloor heating systems. Though
they look similar, these models are distinct in features and application
scenarios. Understanding their functionalities, wiring compatibility, and role
in system topology is crucial for proper installation and use.

Wiring Setup and Use Cases
HTRP230(50) is intended for 4-wire installations, allowing it to
function as a MASTER and manage SLAVE thermostats like HTRS230(30).
HTRS230(30) used in a 3-wire setup cannot receive the NSB signal and
thus operates independently (without SLAVE functionality).
In a 4-wire setup, HTRS230V(30) can switch between comfort and eco
temperatures based on NSB signal from a MASTER unit such as HTRP230.
Example Application Scenario
System with Master/Slave Control:
HTRP230 as MASTER (4-wire setup),
HTRS230 as SLAVE (AUTO mode activated),
Connected via KL08NSB wiring center,
Master thermostat dictates schedule, slaves only
adjust output based on NSB signal.
Summary
HTRP230 is suitable for those needing weekly
programming and system management.
HTRS230 fits simple or subordinate roles within
the heating system.
The “WB” suffix does not change core
functionality but might indicate OEM or mounting variant.
Ensure proper wiring setup (3-wire vs. 4-wire) to
unlock full functionality.
For advanced installations or mixed systems,
refer to the specific KL06/KL08NSB wiring diagrams and consult SALUS support if
uncertain
