B1 - Microclimate Dimming Thermostat

B1 - Dimming Thermostat

Dimming thermostat for controlling upto 600 wats of any heat source. Size 101x78x41 mm (excluding cables)

CHOICE OF HEATER

The B1 are dimming thermosats designed specially to control mains voltage filament lamps. e.g reflector bulbs. However can be also used with any resistive heat source. Do not use with flurescent 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 specifed. To do so may result in damage to the thermostat.

CONNECTIONS

Connect the main 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 failure. The mains cables fitted to the thermostat are colour coded as follows. (brown-live) (blue-neutral) (green/yellow)

INSTALLATION

Position the B1 sensor in the vivarium at a point that you require the temperature to be controlled. This is usually approximately in the centre of the vivarium. This giving your vivarium a gradient of temperature 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

The B1 thermosat has two led indicators, the green power indicator led will be on whilst the thermostat is connected to the main supply. The yellow led indicted 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 blase screwdriver can be used to adjust the temperature control poy on the lid of the B1 thermostat. ALL THERMOSTATS It is understood that some installations may require the removel of the thermostats mains socket for the connection of the heater. However this is not reccommended.
