Heatmiser DS1 v2 Manual Dial Thermostat - Surface Mount 230V Room Thermostat

Description

The Heatmiser DS1 v2 is a simple, reliable manual dial thermostat ideal for conventional and combi-boiler heating systems. It is used in conjunction with a separate programmer or time clock, giving straightforward on/off temperature control for a single heating zone.

Featuring power-on and heat-on indication, an easily adjustable dial and a variable switching differential of 1, 2 or 3°C, the DS1 v2 is a practical, no-frills replacement for older or faulty room thermostats. It is surface mounted, making installation straightforward without the need for a flush-mount back box.

Requires a Separate Programmer

The DS1 v2 is a standalone dial thermostat and does not include onboard time programming. It should be used alongside a separate time clock or programmer to control when the heating system operates.

Qualified Installation Required

This thermostat is powered from a 230V AC supply. Installation must be carried out by a qualified electrician or heating engineer in accordance with current UK wiring regulations.

Simple Dial Operation

An easy-to-use rotary dial lets users increase or decrease the required temperature at a glance.

Power & Heat-On Indication

Clear power-on and heat-on indicators confirm at a glance that the thermostat and heating system are operating correctly.

Variable Switching Differential

A choice of 1, 2 or 3°C switching differential allows the response sensitivity to be tuned to the property and system.

Surface Mount Installation

Designed to be surface mounted directly to the wall, without requiring a flush-mount back box.

Remote Air Sensor Option

Supports an optional remote air sensor probe for flexible sensing away from the thermostat body.

Compatible with Conventional Systems

Does the DS1 v2 include its own timer or programmer?

No, the DS1 v2 is a standalone dial thermostat and is intended to be used alongside a separate time clock or programmer.

What is a switching differential and why does it matter?

The switching differential is the temperature swing before the heating switches on or off again. The DS1 v2 offers 1, 2 or 3°C settings, letting you balance tighter temperature control against fewer boiler cycling events.

Is this thermostat surface mounted or flush mounted?

The DS1 v2 is designed to be surface mounted directly onto the wall, so a flush-mount back box is not required.

Can I use a remote sensor with this thermostat?

Yes, the DS1 v2 supports an optional remote air sensor probe for situations where remote temperature sensing is preferred.

What temperature range does it cover?

The DS1 v2 covers a 5-35°C adjustable temperature range.
