BN35 radio thermostat with timer
The convenient solution for thermostat and time control of your electric heating or cooling units
A constant feel-good temperature – reliably regulated
Using the radio thermostat BN35 from Trotec as remote control, you can easily determine at which room temperature electric heaters or air conditioners shall be switched on or off. The convenient time control of electrical devices with integrated thermostat is also possible.
You can control the switch-on and -off of just one or several devices at a time. The (unobstructed) radio range amounts to approx. 20 metres. It allows you to simultaneously control up to 100 radio-controlled sockets (receivers) with just one radio thermostat (transmitter) – always provided that they are situated within reach. With the timer function you can ensure an agreeable air temperature in a room before even entering it – ideal for the cold kitchen in the early morning, for bathrooms, guest toilets, basement hobby rooms, conservatories, office spaces etc.
Here's how it works:
The BN35 set comprises a radio-controlled socket and a radio thermostat. Simply plug the radio-controlled socket in between a wall outlet and your electrical device. Now you can use the radio thermostat as remote control to set the desired switch-on or switch-off temperature. The radio thermostat measures the room temperature at the current location and accordingly switches the heater or air conditioner on or off to reach the desired target temperature value. Upon reaching the predefined room temperature, the radio thermostat switches the connected electrical appliance off until another cooling or heating cycle is required.
Furthermore, you can make use of a separate or combined time control so as to specify temperature-dependent switch-on/off times in advance. An energy-saving and budget-friendly solution! The BN35 offers you endless possibilities.
The BN35 – all functions and characteristics at one glance:
Using the radio thermostat in heating or cooling mode you can specify the desired target temperature ranging between 0 °C and 70 °C in fine increments of 1 °C (or Fahrenheit). Of course, in order to actually reach the desired room temperature, the connected heating or cooling unit must have a sufficient performance capacity. A scheduled, time-controlled switch-on and switch-off of the connected devices can also be accomplished.
Suitable for a wide variety of heating and cooling units
The BN35 is ideally suited for the majority of eating and cooling units on the market. These include infrared radiant heaters, heating panels, fan heaters, PTC ceramic heaters, convectors, oil-filled radiators, air conditioners, air coolers, fans or even electric towel dryers in the bathroom. The customary maximum load of up to 3,680 watts is fully supported by the BN35.
Range of up to 20 m
The radio thermostat is your remote control. Even radio-controlled sockets located at a greater distance can easily be controlled from your present position. The range amounts to max. 20 metres, however, there should be no obstacles which could weaken or interrupt the radio signal.
1 radio thermostat for up to 100 radio-controlled sockets
Up to 100 radio-controlled sockets can be controlled wirelessly with just one radio thermostat. All radio-controlled sockets situated within the 20 m range will be tripped simultaneously by the radio thermostat. Hence, the set is ideally suited for use in greenhouses or halls. The corresponding radio-controlled sockets of type BN35R can be obtained from Trotec as separate accessories.
Thermostat mode and timer can be combined
Both thermostat mode and timer can be used separately or cleverly combined. By way of example, you can set a heater to be running on Monday between 3 and 5 p.m. and heat a room to 25 °C. At the scheduled time, the radio thermostat will measure the room temperature using its integrated sensor and then switch on the electric heater via the radio-controlled socket to heat the room. But, if the air temperature already corresponds to the desired value, the heater will only start up when falling below the preset 25 °C. An energy-efficient solution – for the device only heats as and when required. Be it at specified times or in continuous operation – with the BN35 you are always in control of when and at which temperature you want to start heating or cooling.
Switched off for the night and back on in the morning
Devices already equipped with an integrated thermostat can use the BN35's timer function. There is no need for heating or cooling devices to be running all night while you're sleeping. To keep from consuming any unnecessary energy you can set the timer in a way that the connected device will be switched off at 10 p.m. and back on at 7 o'clock the next morning.
6 options for timer programming
The radio thermostat allows you to preset up to 6 different automatic timer programmes per day. For each individual programme, you can select on what day and at what time the timer will be activated and deactivated automatically. There are 4 options for selecting the days: You can either select one single day of the week (Mon, Tue, Wed, Thu, Fri, Sat, Sun), only working days (Mon – Fri), only the weekend (Sat – Sun), or the entire week (Mon – Sun).
The radio thermostat always measures the current room temperature of its surroundings. To make sure the sensor can detect the temperature correctly, it is important to be mindful of where the radio thermostat is positioned. On a window sill, for example, exposed to direct sunlight it will generally be warmer than in the centre of the room. A fireplace or radiator should not be in the immediate vicinity either. Therefore, it is advisable to perform the temperature measurement of a radio thermostat from a position promising a realistic measured value.
Everything under control
Used as mobile version, quickly at hand wherever you go, or for stationary application mounted to the wall: the backlit LCD display of the radio thermostat indicates the current time and room temperature, battery status (2 AA batteries) and – depending on the mode – all relevant setting options, time periods, target temperatures etc. As a result you will always be able to keep track of the set parameters.
Frost protection function
Should the ambient temperature of the radio thermostat drop to 3 °C or below, a frost protection mode, which ensures that the room temperature is increased to 5–7 °C by the heater connected to the radio-controlled socket, is activated automatically. In this manner, e.g. water pipes in unheated rooms are protected against icing up.
Can also be controlled manually
You can also switch your connected heating or cooling unit on or off by pressing a button directly at the radio-controlled socket. However, this rules out the operation with thermostat function.
Saving energy by means of a permanent consumer switch-off function (OFF)
To make sure that an electrical device really is turned off and no longer consumes power (no stand-by operation), the power supply can be reliably interrupted owing to the 2-pin circuit breaker.
Automatic switch-over from daylight saving to standard time and vice versa
Using the DST option, the radio thermostat will automatically switch over from daylight saving to standard time and vice versa. Which means that you need not think about anything with regard to the time change twice a year, your preset time intervals will be adjusted automatically. For it is by no means certain whether we will really say goodbye to daylight saving in all of Europe by 2021.
