The B1
Choice of heater
The B1 is a dimming thermostat designed specifically to control mains voltage filament lamps e.g. Reflector bulbs. However they can also be used with any resistive heat source. Do not use with fluorescent or discharge lamps. The thermostat can control loads of 5 watts up to a maximum of 600 watts. Do not attempt to operate the B1 with a greater load than specified. To do so may result in damage to the thermostat.
Connections.
Connect the mains cable from your heat source to the heater output of the B1 (fitted mains socket) using a suitable 13A plug (fitted with a 3A fuse).
Connect the B1 to the mains supply using the fitted mains plug.
Please note the mains plug is fitted with a 3A fuse which must be replaced with a 3A fuse in the event of a failure.
The mains cables fitted to the thermostat are colour coded as follows :-
(Brown-Live) (Blue-Neutral) (Green/Yellow-Earth)
Installation.
Position the B1 sensor in the vivarium at the point that you require the temperature to be controlled. This is usually approximately in the centre of the vivarium. Thus giving your vivarium a gradient of temperatures i.e. Hotter at the heat source end, controlled temperature in the middle and cooler at the end furthest away from the heat source. Do not position the sensor directly in front of the heat source . This is to ensure the sensor is measuring air temperature and not direct heat.
Always use a thermometer to check the temperature of the vivarium and adjust the B1 as required to give the required temperature.
Indication of operation of B1 thermostat
The B1 thermostat has two led indicators, the green power indication led will be on whilst the thermostat is connected to the mains supply.
The yellow led indicates power is being supplied to the heater. In normal operation the yellow led will increase or decrease its brightness in proportion to the power being supplied to the heat source, this indicates that the heater source is being controlled at the desired temperature. When first switched on it will be noted that the yellow led is on full brightness indicating that the heater source is on full power whilst attaining the set temperature. If the yellow indicator remains in this state for a long period of time it would suggest that the heat source is not able to raise the temperature to the desired level and a larger heater or a second heat source should be installed.
Adjustment.
A small flat blade screwdriver can be used to adjust the temperature control pot on the lid of the B1 thermostat.
The B1 is guaranteed for a period of 12 months from the date of purchase.
In the unlikely event of a component failure -: if less than 3 months old the thermostat will be replaced. If over 3 months old the thermostat will be repaired free of charge. In order for the guarantee to be valid this instruction sheet must have been followed.
We reserve the right to repair rather than replace any thermostat that has been altered in any way.
All thermostats
It is understood that some installations may require the removal of the thermostats mains socket for the connection to the heater. However this is not recommended.
Exceptions to the guarantee
The guarantee will be void if the B1 has been misused i.e. Over loaded, or physical damaged.
This does not affect your statutory rights
The B1 range of thermostats have been designed to last for many years if set up and used correctly.
Due to the universal application of this product, no liability for loss, injury to livestock or damage to equipment etc, or consequential loss can be accepted.
