Product Details
ICM Controls ICM2910-205-021 Fenwal OEM Replacement DSI Control, 35-725205-021Direct Spark Ignition (DSI) control modulesThe ICM2910 consists of a series of 11 Fenwal OEM Replacement DSI Controls. When the thermostat initiates a “Call for Heat”, the ICM2910 will perform a hardware check. After the hardware check, the ICM2910 will start a pre-purge where applicable.Once the pre-purge has ended, the spark source and the gas valve relay are energized simultaneously for the duration of the trial for ignition period. A flame rectification circuit confirms the presence of the flame. Upon flame detection, the spark source is turned off.If flame is not sensed, the control will turn off the spark source and gas valve and start an inter-purge where applicable before the next trial for ignition. If flame is not detected after the trial(s) for ignition, the control will enter a hard lockout. To clear the hard lockout, remove the input voltage to the control or recycle the thermostat’s heat call.Direct Spark Ignition (DSI) control modulesMicroprocessor-basedControls spark ignitor and gas valveMonitors timing, trial for ignition, flame sensing and lockoutCompatible with LP or natural gasRedundant Gas valve design conforms to ANSI Z21.20Conforms to UL STDs 60730-1 and 60730-2-5.Certified to CSA STD E60730-1 and CSA STD C22.2#60730-2-5SPECIFICATIONSControl Voltage:102-138 VACFlame Current:1uA minimumCurrent Draw:50mA maximumGas Valve:1.5A@120 VACFlame Failure Response Time:0.8 seconds maximumOperating temperature:-40˚F to 175˚F (-40˚C to 80˚C)Dimensions:5.23”L x 2.53”W x 1.86”HMounting:Surface mount using (2) #8 screws**Picture is for representation only and may vary slightly**Sell SheetInstallation Manual
