Ultraflex CRM Control Panel — Install & Maintenance Guide (Motorized Window/Skylight Systems)

Complete install & maintenance guide for the Ultraflex Control Systems (UCS/FFI) CRM Control Panel and Weather Detection System — for motorized window and skylight actuators. Covers the CRM3 (DC actuators, part# 40821J) and CRM4 (AC actuators, part# 40822K).

CRM Applications

• The CRM includes a control relay box and power supply — no additional relay box or power supply needed unless capacity is exceeded (4 amp for CRM3, 7 amps for CRM4).
• Adds Remote Control capability to actuator(s).
• Adds Weather Sensor capability (rain, wind, thermostat) to actuators.

CRM Specifications

*FFI recommends not exceeding 80% of maximum amp capacity for control panels.

Safety Notices

1. Read this guide carefully prior to installation.
2. Keep these instructions for later review after installation.
3. Incorrect application or improper installation may result in system malfunction and/or damage to people or property.
4. To avoid electrocution when the CRM cover is removed, verify the CRM is disconnected from the power circuit before making electrical connections at internal terminals or performing any other operation.
5. It's recommended the CRM be connected to a dedicated power circuit.
6. Installation must be done by licensed electricians and/or engineers.
7. Prior to installation, confirm the existing electrical system complies with local building codes, and that the power supply is compatible with the CRM's specifications.

Warnings

• Do not attempt to repair the CRM Control Panel. Contact FFI Customer Service at 800-677-0228 or service@fenestration.net for a malfunction. The two-year warranty is provided by Ultraflex Control Systems (UCS).
• The CRM control panel, keyboard, remote control, and thermostat are for indoor use only — not recommended for high-humidity areas like greenhouses. Rain and wind detectors can be installed outdoors.
• To be covered by warranty, UCS actuators must be used with UCS-approved accessories (power supplies, control panels, control boxes, relay boxes, weather detectors, switches, etc.).

Installation Overview

The CRM3 (24 Vdc Control Panel, part# 40821J) delivers power directly to low-voltage actuators, or serves as a switch for multiple RB24 Relay Boxes. It independently controls 1–4 actuator groups via output terminals M1-M4, subject to a max current draw of 4 amps across any combination of the 4 terminals. Input power is 115 Vac, 60Hz; a back-up power source can be connected at the JP4 terminal inside the case.

The CRM4 (115 Vac Control Panel, part# 40822K) delivers power directly to line-voltage actuators. It independently controls 1–4 actuator groups via M1-M4, subject to a max current draw of 7 amps across any combination. Input power is 115 Vac, 60Hz; a back-up power source can also be connected at JP4.

The Control Panel's four actuator groups start up sequentially to eliminate excess current draw risk.

Control Accessories & Alarm States

The Control Panel receives commands from optional accessories, which can trigger an "alarm state" causing actuators to close the windows. Alarm State 1 persists for a minimum of 8 minutes, during which windows cannot be opened via Keypad, Momentary Switch, or External Control System (unless rain/wind sensors are disabled).

Installation Procedure

Check that the Control Panel's electrical fuses are in place (see Fuse table below).

Momentary Contact Switch / External Control System

A single-pole double-throw (SPDT) momentary contact switch or external control system connects at terminal JP7, delivering OPEN/CLOSE commands as brief impulse signals (0.5–2 sec). The Control Panel acts on all four actuator groups, as if commanded from a Keypad with all 4 LEDs on. Both Keypad and Momentary Switch can be connected simultaneously. Wall switch spec: 15 amps max draw per switch (DC motors with CRM or relay box); dimensions 4" x 1-1/4" x 1-1/2".

Push-Button Keypad (Part # 40770K)

Connects at terminals JP5/JP6; multiple keypads can be wired in parallel. Dimensions: 3" x 3" x 1-1/2". Allows independent control of 1–4 actuator groups via serial communication.

Use SELECT to light 1, 2, 3, 4, or all 4 LEDs (one per actuator group), then press OPEN or CLOSE to activate; press the opposite button once to stop the motor. The Control Panel delivers power for a 3-minute interval, then cuts off as a safety precaution. The Keypad has an 8-channel IR detector for the Remote Control — channel 0 (factory default) accepts all frequencies; channels 1-7 restrict to that channel only.

Remote Control (optional, Part # 40771L)

Uses serial protocol and line-of-sight IR signals — must be pointed at the Keypad, not the actuator. Effective range ~30 feet. Requires two 1.5V AAA alkaline batteries (not included). Dimensions: 4" x 1-13/16" x 1". Has an 8-channel IR transmitter matching the Keypad's channel setting (0 = factory default).

Wind Detector / Anemometer (optional, Part # 37185V)

Connects at terminal JP9, sending a variable signal per wind intensity. An 8-position selector inside the Control Panel sets the closing threshold ("0" disables; 1-7 correspond to the Beaufort scale). One sensor can serve up to six CRM Control Panels. Disable via the external switch on the Control Panel case. Dimensions: 4-1/2" x 4" x 4".

Thermostat (optional, Part # 40675K)

Single threshold setting — windows open when ambient temperature rises above threshold, close when below. Rain and wind sensors take priority over the thermostat. Disable via the external ON/OFF switch on the thermostat case. One thermostat can connect to up to six CRM Control Panels. Dimensions: 3" x 3-1/4" x 1-1/2".

Rain Sensor (optional, Part # 40690A)

Connects at terminal JP8. One sensor can connect to up to six CRM Control Panels. Mount outdoors with the copper-colored grid exposed to the sky. Dimensions: 1-1/2" x 2" x 2". Has a heating element to prevent ice formation.

• Consider prevailing winds and keep away from obstructions when siting.
• Do not run wiring through a window screen opening occupied by the actuator's chain, or near the chain's path.
• Rain and wind sensors take priority over the thermostat. Disable via the external switch on the Control Panel case.
• Do not use the rain sensor if the actuator serves Smoke Ventilation.
• Clean the sensor's copper grid regularly with mild soap and water — dirt/debris can trigger false alarm states, keeping vents closed even when it's not raining.

Actuator Connections

Actuator groups connect at output terminals M1, M2, M3, M4. CRM3 (24 Vdc, part# 40821J) delivers power directly to DC low-voltage actuators or switches multiple RB24 Relay Boxes, controlling 1–4 groups at up to 4 amps combined. CRM4 (115 Vac, part# 40822K) delivers power directly to AC line-voltage actuators, controlling 1–4 groups at up to 7 amps combined. Both require 115 Vac, 60Hz input; a back-up power source connects at JP4 in either case.

Control Panel Fuse Locations

RB24 Relay Box (for 24V DC motors only)

A passive device controlling low-voltage actuators via output terminals Motor1 and Motor2, up to 10 amps per terminal (20 amps per Relay Box). It handles polarity reversal for Motor1/Motor2. An SPDT momentary contact switch or external control system connects at terminal CN6, delivering OPEN/CLOSE impulse signals (0.5–2 sec) that operate all actuators on the Relay Box.

• With Jumper In Place (One Touch Switch Operation): Press the switch once — the RB24 powers actuators for a 3-minute interval, long enough to fully open or close. Press the opposite-direction switch to stop the motor.
• With Jumper Removed (Press & Hold Operation): Press and hold the switch until fully open/closed; release to stop.
