IN ORDER TO AVOID ANY RISK OF ELECTRIC SHOCK, TURN OFF THE POWER TO THE HEATING
SYSTEM BEFORE COMMENCING INSTALLATION.
1. Separate the front part of the thermostat by placing a small at head
terminal driver into the slots on the bottom face of the thermostat.
2. Terminate the thermostat as shown in the wiring diagram.
3. Screw the back plate securely back onto the wall.
4. Clip the front part of the thermostat onto the back plate and turn the power back on.
The Heatmiser DS-SB is a ush mounted set-back thermostat and is ideal for those
who want a simple but energy ecient temperature control system. The DS-SB
features a set-back function. This function automatically reduces the set temperature
by 4°C when no time clock signal is detected.
The DS-SB thermostat has been designed to work in conjunction with the Heatmiser
UH3 wiring centre and TM4 Programmer, but can also be used as a standalone dial
thermostat.
The Heatmiser DS-SB provides the option to work with a remote temperature sensor.
When a compatible remote sensor is connected, the thermostat will automatically
switch from using it’s internal sensor to use the remote sensor instead. This function
is ideal for controlling bathrooms or when the thermostat needs to be installed in a
dierent area of the building to that being measured and controlled.

PDF FAQ

To change the set point, rotate the dial until it points to the desired temperature. The Heatmiser DS-SB oers a set-back function that automatically reduces the set
temperature by 4°C.
To make use of the set-back function, a 230v time clock is also required on the system.
Place the thermostat slide switch into the time clock position.
When the thermostat receives a 230V signal from the time clock it will control the
temperature according to the dial setting.
When no 230v signal is received from the time clock, the thermostat will operate in set-
back mode and automatically reducing the set temperature by 4°C

The time clock can be bypassed by placing the switch into position 1.
In this position, the thermostat will ignore the time clock input and will continuously
control to the set temperature. This feature can be used to extend the heating period
without the need to adjust the time clock program.
Placing the thermostat switch into position 0 will turn OFF the heating completely.
