QI2-EMST-100RF Thermostat

GENERAL INFORMATION The thermostat normally displays room temperature, mode of operation andwhether cooling or heating is currently on. The six buttons on the front of theunit allow complete control of your equipment.You may select different heating and cooling setpoints for the system tomaintain, e.g., 70° in heating and 75° in cooling. Raising or lowering the set-points in heating or cooling is as simple as pushing a button. In addition, youmay choose to display the temperature in °F or °C.The thermostat also allows you to select continuous fan operation (usefulwhen using an air cleaner) or have the fan come on with the equipment. BUTTON FUNCTIONS SYSTEM Press to select COOL only, HEAT only, AUTO (cool andheat), OFF, or EMERGENCY HEAT (heat pump installations only). FAN Press for continuous fan or auto fan OCCUPANCY Press to select HOME (Occ1), AWAY (Occ2), SLEEP(Occ3), VACANT (Occ4), or User Defined (USr1-USr4) occupancy modes. HOLD/RESUME Press to alternate between HOLD OVERRIDE andRESUME program. Operating Instructions Single/Multistage Conventional or Heat Pump with Auxiliary Heat Electronic Digital Communicating Non-Programmable Thermostat HEATING  Select the temperature you want your equipment to maintain while inthe heating mode by pressing and holding the  or  buttons. The control setpoint temperature is displayed for 5 seconds.FAN The fan will come on automatically when the system is operating,but there is no indication of this on the display. To select continuousfan operation, press the FAN button and the display will show . This is recommended for electronic air cleaners and continuous ven-tilation requirements.OFFTo turn off the heating or cooling system, press the MODE buttonuntil the word OFF appears on the LCD. It will remain displayed untilthe mode is changed. The OFF mode prevents the system frombeing energized.Avoid using the OFF mode during extremely cold weather to prevent damage to the equipment from freezing.AUTO CHANGEOVERYou may set the thermostat to automatically switch from heating tocooling mode by pressing the MODE button until the word AUTOand both the heating  and cooling icons appear on the LCD. The thermostat will energize the heating or cooling system based on thetemperatures established for both modes. USER CONTROLS (CONT’D) TEMPORARY TEMPERATURE OVERRIDE Press the  or  to temporarily raise or lower the setpoint until the next scheduled setpoint change.HOLD TEMPERATURE OVERRIDEPress the HOLD/RESUME button to change a Temporary Override to a Hold Override. This will prevent scheduled setpoint changes.Press HOLD/RESUME button again to resume scheduled setpoint changes.CELSIUS / FAHRENHEITSimultaneously press  and  to switch between Celsius (C) and Fahrenheit (F) temperature display.REMOTE SENSOR (OPTION)RS1 – RS2 – RS+VThe thermostat is designed to accept the electronic remote sensor,which will allow you to locate your thermostat in an area away fromview. Indoor and outdoor sensors are available separately.TEMPERATURE ACCURACYFull temperature accuracy will be realized only after the thermostathas been installed and powered for at least one (1) hour. NOTES: ADD-ON HEAT PUMPSYour DSL thermostat is equipped to enhance the performance of anadd-on heat pump. Your thermostat, in most applications, will performthe function of a fossil fuel kit.To select add-on, place switches #3 and #5 to the ON position. Thethermostat will turn the compressor off with a call for auxiliary heat.When switch #5 is set to normal (OFF), the thermostat will allow thecompressor and the auxiliary heat to be on at the same time.POWER FAILURESYour thermostat employs the latest in solid state electronic technology.One of the unique features of your thermostat is that no battery isrequired to maintain your selected setpoints in the event of a power lossas the memory is unaffected by power failures of any duration.When power is restored, the thermostat will continue operating as if thepower had never been off. USER CONTROLS SYSTEM – Select the desired mode of operation by repeatedly pressing the MODE button: – indicates cooling system only (the word COOL is displayed for 5 seconds)  – indicates heating system only (the word HEAT is displayed for 5 seconds)  – indicates both the heat and cool systems (the word AUTO is displayed for 5 seconds) Blinking – indicates cool ON  Flickering – indicates heat ON OFF – disables controller so equipment will not operate (fan operation is still possible in this mode)E Ht - Emergency heat (heat-pump installations only). COOLING Select the temperature you want your equipment to maintain while in thecooling mode by pressing and holding the  or  buttons. The control setpoint temperature is displayed for 5 seconds. 2 3 4 5 6 7 1 (One) Year Limited Warranty The manufacturer warrants to the original purchaser that its product and component parts will be free from defects in workmanship and materials for aperiod of 1 (one) year from the date of purchase.

FCC ID: QI2-EMST-100 Invensys HCS Thermostat 1 of 16 900MHz FHSS EMISSIONS TEST REPORT FOR A LOW POWER TRANSMITTER I. GENERAL INFORMATION Requirement:Federal Communications Commissions Test Requirements: 15.205, 15.207, 15.209, 15.247 Applicant: Robertshaw Controls Company d/b/a Invensys Home Control Systems Product ID: FCC ID: QI2-EMST-100 II. DESCRIPTION OF EQUIPMENT UNDER TEST (EUT) The Invensys FCC ID: QI2-EMST-100is a frequency hopping spread spectrum (FHSS) transceiver. The Invensys “RF Thermostat” unit provides monitoring, management and control of a residential HVAC system. It utilizes an iCon Thermostat transceiver module to communicate with the RF Gateway unit The Thermostat Transceiver Module operates in the U.S. ISM band between 902 and 928 MHz. The module incorporates a microcontroller and an r.f. integrated circuit that form a frequency hopping spread spectrum transceiver operating under FCC part 15.247. . Transmitter Specification TX Power12dBm Frequency Deviation (FSK)+/- 20 kHz Frequency of operation905 – 924.6 MHz Data Rate19.2 kbps Number of channels50 Channel Separation400 kHz Typical 20dB occupied bandwidth 150 kHz III.

Antenna connector requirement The antenna is permanently attached to the product. 15.204 Antenna description The thermostat transceiver module uses a printed circuit folded dipole antenna: Antenna descriptionGainMFR name HCST printed ckt antenna5.64 dBi maxInvensys HCS Measured antenna data and radiation patterns are presented in a separate pdf attachment. 15.247(a) Frequency hopping spread spectrum definition Pseudorandom frequency hopping sequence: The transmitter cannot coordinate its hopping sequence with the hopping sequence of other transmitters, or vice versa, for the purpose of avoiding the simultaneous occupancy of individual hopping frequencies by multiple transmitters Each access unit has an individual ID number and there is no link or association between two access units so there is no simultaneous occupancy of individual hopping frequency transmission of two or more access units. Equal hopping frequency use: The EUT utilizes 50 hopping channels. Hopset is 50 channels long, then repeats. On average all channels are used equally. System receiver input bandwidth and receiver hopping capability: Receiver 26 dB bandwidth is 200 kHz, approximately equal to 26 dB bandwidth of TX. Receiver channel hops are synchronized to transmitter operating frequency.

The EUT was placed on a wooden table resting on a turntable on the open air test site. The search antenna was placed 3m from the EUT. The EUT antenna was mounted vertically as per normal installation. 2. The turntable was slowly rotated to locate the direction of maximum emission at each emission falling in the restricted bands of 15.205. 3. Radiated emissions were investigated for a LOW channel, a MID channel, and HIGH channel. Emissions were investigated to the 10 th harmonic. 4. Once maximum direction was determined, the search antenna was raised and lowered in both vertical and horizontal polarizations. The maximum readings so obtained are recorded in the data listed below. Test Results: Worst case results are presented. Refer to data sheets in separate attachments. Restricted band emissions meet 54 dBuV/m. Other undesired emissions from the transmitter meet the -20 dBc requirement in 15.247(c). 24-26 July 2002Engineer;C.
