Troubleshooting

The heater boost resets itself off:
• The supply to the heater boost switch must be permanent, it
should not be wired in series after another timer device.
The main heating timer is not functioning:
• The heater boost switch can only be wired in parallel with relay
output timer units, otherwise the output of the other timer may be
damaged.

Plated heater boost switch

TLSW HB TLSW HB BP
DANLERS plated heater boost switch can be mounted onto a standard
back box and needs a neutral connection. It can switch a resistive
heating load up to 3kW.
The plate incorporates four red LEDs, each representing a different
remaining time range. Each time the button is pressed the remaining
time advances to the next value, giving a longer time lag. If the button
is pressed when the fourth LED is lit the load is switched off.
The four time lags periods are as follows:
TLSW HB Marked plate with ¼, ½, 1 and 2 hour periods
TLSW HB BP Blank plate with ¼, ½, 1 and 2 hour periods
TLSW HB BP1246 Blank plate with 1, 2, 4 and 6 hour periods
The heater boost switch can be wired in parallel with any other relay
output timers as a manual override.

These switches can only be connected to a 230V, 50Hz ac supply.
They can switch up to 13 amps (3000W) of Resistive loads
Or they can also switch up to 1 amp (250W) of fans
For larger loads they can be used to operate a contactor.

Installation procedure
