Product Overview

PROGRAMMER DIPSWITCH SETTINGS

NOTE: THE DIPSWITCHES ARE A ONE TIME, ONE SHOT SETTING. ONCE THE

DIPSWITCHES ARE SET AND THE PLASTIC WINDOW IS MOVED OVER THE

SWITCHES, THE WINDOW CANNOT BE MOVED AND THE DIPSWITCHES AND THEIR SET-

TINGS CANNOT BE CHANGED WITHOUT CAUSING THE CONTROL TO BECOME INOPERA-

BLE.

The MP230, MP230H, and the MP560, MP561, MP562 Programmer Modules have a series of 8

dipswitches which allow the user to program the purge timing, trial for ignition timing, and recycle/

non-recycle operation of the control. These dipswitches are programmed only ONCE, before the ini-

tial operation of the control.

THE PLASTIC WINDOW MUST BE MOVED OVER THE SWITCHES IN ORDER FOR

THE PROGRAMMER TO OPERATE BEYOND PURGE.

Purge Timing

Dipswitches # 1 through #5 are used to select the purge timing for the control. The available timing

selections are 5 seconds, 7 seconds, 30 seconds, 60 seconds, 240 seconds, and any combination of

those timings. The timings for these switches are additive. Selecting two or more purge timing

switches will result in a purge timing period equal to the sum of the switches (e.g. selecting switches

# 3, and #4 will cause a purge timing of 90 second: 30 seconds plus 60 seconds). To select the timing

associated with a particular switch, move the switch to the RIGHT (On Position).

NOTE: If all 5 switches are set to the OFF position, the control will lock out after the air flow switch

has been proven closed.

Trial for Ignition

Dipswitches #6 and #7 are used to select the trial for ignition timing for the control. The available

timing selections are 5 seconds and 10 seconds only. See Figure #1. Select ONLY ONE of these two

switches. These switches ARE NOT additive. To select the timing associated with a particular

switch, move the switch to the RIGHT (On Position).

NOTE: If both switches are set to the OFF position, the control will default to a trial for ignition

period less than 5 seconds (e.g.: 3-4 seconds).

If both switches are set to the ON position, the control will default to LOCKOUT.

Recycle/Non-recycle Operation

Dipswitch #8 is used to select either recycle or non-recycle operation of the control. (See APPLICA-

TION AND FUNCTION). To select RECYCLE operation, move the switch to the LEFT. To select

NON-RECYCLE operation, move the switch to the RIGHT.
