| Models | EP100S, EP200S, EP300S, EP160, EP161, EP163, EP170, EP174, EP165, EP166, EP177, EP260, EP265, EP270, EP380, EP381, EP382, EP383 |
| Category | Programmer & Amplifier Modules |
| Approvals | cULus, FM Approved |
| EP163, EP177 | Programmable via the ED510 Display Module, offering advanced configuration options. |
| Safety Checks | Includes open damper (high purge) prepurge, proof of low fire position, and fuel valve end switch safety checks. |
| Dipswitch Settings | Most modules feature six dipswitches for configuring operational characteristics: Forced Blower Motor Start Delay (Dipswitch 1, inactive for some models) Extended Purge Timing (Dipswitches 3, 4, 5) 3-P Running Interlock Circuit Requirement (Dipswitch 6) For models EP163, EP177, and EP383, settings are managed via the ED510 Display Module instead of dipswitches. |
| EP260, EP265, EP270 | Include essential start-up and safety checks with configurable dipswitch settings. |
| EP100S, EP200S, EP300S | Configurable via dipswitch settings. |
| Running Interlock Circuit | Continuously monitors limit switches, airflow switches, and fuel pressure switches. If any circuit opens at an inappropriate point, the control initiates a safety lockout or recycling process (depending on model settings). |
| EP160, EP161, EP170, EP174 | Provide robust safety and control features with configurable dipswitch settings. |
| Flame Monitoring Supervision | Monitors flame presence for safe operation. |
| EP380, EP381, EP382, EP383, EP390 | Feature extended purge timing and configurable operational modes, with the EP383 programmable via the ED510 Display Module. |
| Start-Up Programming And Safe-Start Check | Ensures proper ignition sequence and system readiness. |
