SALUS DT600RF Wireless Programmable OpenTherm Thermostat

Description

The SALUS DT600RF Wireless Programmable OpenTherm Thermostat gives you precise, weather-responsive control over your heating system using genuine OpenTherm communication between the thermostat and a compatible boiler. Rather than simply switching the boiler on and off, OpenTherm allows the DT600RF to modulate the boiler's flow temperature to match the exact heat demand in the room, helping to reduce energy wastage and cut running costs.

Built around a TPI (Time Proportional and Integral) control algorithm with built-in optimisation functions, the DT600RF learns your heating system's response time and adjusts start and stop points automatically so rooms reach target temperature exactly when needed. It communicates wirelessly over 868MHz two-way RF with feedback confirmation between thermostat and receiver, and is Boiler Plus compliant for UK combi boiler installations.

Good to Know

OpenTherm communication only delivers full modulating benefit when paired with an OpenTherm-compatible boiler. On boilers without OpenTherm support, the DT600RF still operates as a highly accurate on/off room thermostat using its TPI algorithm.

OpenTherm Boiler Communication

Built-in OpenTherm (OT) circuit modulates boiler flow temperature to match real-time heat demand, rather than simple on/off switching.

Optimisation Algorithms

Start/stop optimisation learns your home's heating response time so target temperature is reached exactly when scheduled, not before or after.

Landlord PIN & Service Mode

A PIN-protected lockout function restricts access to programming settings — ideal for rental properties, HMOs, and shared or commercial premises.

2-Way RF Communication

Wireless 868MHz two-way communication confirms that commands sent from the thermostat have been received and actioned by the receiver.

7-Day Programmable Schedule

Set individual heating schedules for each day of the week, with multiple on/off periods to match your household routine.

Frost Protection

Built-in frost protection mode keeps the property's minimum temperature safeguarded automatically when the main schedule is switched off.

Please Note

The DT600RF is not suitable for underfloor heating systems — it is designed for radiator-based central heating control via a compatible boiler or receiver.

Important Safety Information

Installation of the receiver unit involves connecting to mains electrical wiring at the boiler or programmer. This work must be carried out by a competent, qualified installer in accordance with BS 7671 (IEE Wiring Regulations) and Part P of the Building Regulations.

Frequently Asked Questions

Does the DT600RF work with any boiler?

The DT600RF's volt-free and 230V switching makes it compatible with most combi, system, and regular boilers. Full OpenTherm modulating control is only available when connected to a boiler with OpenTherm support — on other boilers it still functions as an accurate on/off thermostat.

Is this thermostat suitable for underfloor heating?

No. The DT600RF is designed for radiator-based central heating systems and is not suitable for underfloor heating applications.

What batteries does the thermostat use?

The thermostat unit is powered by 2 x AA batteries. The separate receiver connects to a 230V mains supply.

What does the Landlord PIN feature do?

The Landlord PIN lets an installer or landlord lock the programming menu with a PIN code, preventing tenants or occupants from altering the heating schedule or settings.

Is the DT600RF Boiler Plus compliant?

Yes. The DT600RF is Boiler Plus compliant, meeting the UK Building Regulations Part L requirement for combi boiler installations to include a compatible time and temperature control device.

Can I mount the DT600RF on a desk instead of the wall?

Yes. The DT600RF supports both wall mounting and desk-top use, giving flexibility over where the thermostat is placed in the room.
