This unit provides on-off primary control with integrated prepurge functionality, delivering advanced safety, functional capability, and system diagnostics compared to conventional controls. Key functions include automatic burner sequencing, flame supervision, airflow switch checks, and comprehensive nonvolatile memory for history retention.\u003c\/p\u003e\n\u003ch3\u003eSystem Architecture and Required Components\u003c\/h3\u003e\n\u003cp\u003eOperation of this primary control requires specific plug-in components, including a Q7800A or Q7800B universal wiring subbase, an interchangeable plug-in flame amplifier compatible with the 7800 Series, and an ST7800A plug-in purge timer card to determine prepurge timing. Five diagnostic LEDs provide real-time sequence information, while nonvolatile memory retains history files and sequencing status even after a power loss.\u003c\/p\u003e\n\u003ch3\u003eElectrical Ratings and Environmental Performance\u003c\/h3\u003e\n\u003cp\u003eThe control operates on a 120 Vac supply voltage at 50 Hz or 60 Hz frequencies with a ±10% tolerance. It is housed in an enclosure designed to withstand a 0.5 G vibration environment and supports a shipping and storage temperature range of -40 deg C to +60 deg C. The unit carries recognized and certified industrial approvals including UL, CSA, Factory Mutual, and CSD-1 compliance.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eRM7895A1014\/U\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eBurner Mod Primary Control (On-Off Primary Control with Prepurge)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage\u003c\/td\u003e\n\u003ctd\u003e120 Vac (+10, -15%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFrequency\u003c\/td\u003e\n\u003ctd\u003e50 Hz \/ 60 Hz (±10%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlame Establishing Period - Pilot\u003c\/td\u003e\n\u003ctd\u003e4 sec or 10 sec\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFlame Establishing Period - Main\u003c\/td\u003e\n\u003ctd\u003eIntermittent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRequired Components\u003c\/td\u003e\n\u003ctd\u003eQ7800A\/B Subbase, 7800 Series Flame Amplifier, ST7800A Purge Timer Card\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUsed With\u003c\/td\u003e\n\u003ctd\u003e7800 Series Amplifiers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (with Q7800A Subbase)\u003c\/td\u003e\n\u003ctd\u003e127 mm x 127 mm x 133 mm (5 in. x 5 in. x 5 1\/4 in.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions (with Q7800B Subbase)\u003c\/td\u003e\n\u003ctd\u003e127 mm x 127 mm x 155 mm (5 in. x 5 in. x 6 3\/32 in.)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating\/Storage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +60 deg C (-40 F to +140 F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVibration Tolerance\u003c\/td\u003e\n\u003ctd\u003e0.5 G environment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.9 kg (1 lb 15 oz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eShipping Weight\u003c\/td\u003e\n\u003ctd\u003e2 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApprovals\u003c\/td\u003e\n\u003ctd\u003eUL File No. MP268, CSA File No. LR95329-3, FM Report No. OX4A5.AF, CSD-1, Swiss RE, FCC Part 15 Class B\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What mandatory plug-in components are required for the RM7895A1014\/U to operate?\u003c\/p\u003e\n\u003cp\u003eA: It requires a Q7800A or Q7800B universal wiring subbase, a compatible 7800 Series plug-in flame amplifier, and an ST7800A purge timer card.\u003c\/p\u003e\n\u003cp\u003eQ: How does the control retain data during a power interruption?\u003c\/p\u003e\n\u003cp\u003eA: It features built-in nonvolatile memory that retains historical error files and sequencing status after a power loss.\u003c\/p\u003e\n\u003cp\u003eQ: What is the nominal operating voltage for this primary burner control?
