The left handle (cold threshold) controls heat, drag it above the current temperature to turn on heat; the right handle (hot threshold) controls AC, drag it below the current temperature to turn on AC. When the temperature at specified sensor reaches within the "comfort zone" heat/AC are turned off.
Click the upper region once to set cold threshold for comfort zone to ~5°F above current temperature,
press twice to set it ~10°F above, and so on. An orange light indicates heat is turned on.
If AC is currently on, raise the thresholds by 5°F until when blue/orange light both flashes to indicate heat/ac is turned off.
Click the lower region once to set hot threshold for comfort zone to ~5°F below current temperature,
press twice to set it ~10°F below, and so on. An blue light indicates AC is turned on.
If heat is currently on, lower the thresholds by 5°F until when blue/orange light both flashes to indicate heat/ac is turned off.
|Click the upper region while press and holding the lower region to turn on fan. Click twice to increase fan speed. An green light with corresponding intensity indicates fan is turned on.||Click the lower region while holding the upper region to decrease fan speed until fan is off. An green light that rapidly flashes twice indicates fan is turned off.|
Kumostats controls heat/AC using not only readings from its internal precision temperature/humidity sensor, but also temperature readings from any of the Wireless Sensor Tags (motion, water, contact or infra-red) in different rooms in your house or in your garage. You can choose which sensor one to use, or have a KumoApp automatically pick a temperature sensor for you.
Kumostat works with your existing Wireless Sensor Tags utilizing their integrated temperature sensors. In addition, we introduce a new wireless infra-red (PIR) occupancy + high precision (+/-0.4°C) temperature + air humidty sensor "KumoSensor™".
3D compass based Wireless Motion Sensor tags detect any angle change by itself, and can be installed on any moving part of door/window to allow detecting open/close.
But they are not the most reliable way for monitoring door/window opend/closed status, as they report closed when the their angle returns to within a threshold,
not when door/window is completely closed. Since they are based on periodic polling,
if a window is opened and then closed quickly, it may miss the event.
The new Reed KumoSensor™ uses a low power contact-based door/window sensor to send you notification immediately when it is moved away from/back to a matching magnet piece, with 3~5x longer battery life.
Like other KumoSensors they integrate a high precision (+/-0.4°C) temperature and relative humidity sensor. In addition, you can attach an external water-proof temperature probe* using a screw driver.
Some KumoApp can use the location of mobile devices of your choice as triggers. For example, "turn on AC/heat when any one of the phones gets close to a location", or "turn off AC/heat when all of the phones exit a region". Configure these rules easily using our iOS app. Without any KumoSensors, a Kumostat by itself and a Tag Manager (can be shared with other Kumostats) can automate your HVAC to cut the energy bills.
Completely programmable wiring.
Kumostat supports 3 stage heating and 2 stage cooling HVAC systems with fan and reverse valve (7 relays in total.)
Completely programmable wiring allows the 7 relays to be assigned to any kind of desired function. For example, it can be configured to support HVAC systems with
- 2 stage heating / 3 stage cooling
- 2 stage heating / 2 stage cooling / 2 stage fan
- 2 stage heating / 1 stage cooling / 3 stage fan
Solid state relays make Kumostat compact and silent.
Most other thermostats use mechanical relays (switches) that may emit sound when turning on or off. Kumostat uses semiconductor (solid-state) relays that do not have any moving parts. Therefore, operation is completely silent. Our Patent pending circuit steals a small amount of energy from the HVAC control wires to turn on these solid-state relays, allowing long battery life from a single coin-cell battery, even if the blue "C" wire is not connected. The use of solid state relays and coin cell battery makes Kumostat thinner and smaller than other thermostats.
