HL-69158NP Multi-Function Humidity Device

with Temperature Sensor Product Bulletin

Introduction

The Johnson Controls

HL-69158NP is a multi-function

device that can function as a high limit or proportional

override humidity controller, as stand-alone proportional

controller, or a stand-alone two-position controller.

As a high limit or proportional override controller, it limits

duct humidity by comparing a controller’s request for

humidification with the humidity present in a duct. The

HL-69158NP proportionately reduces its output signal to

the humidification equipment as duct Relative Humidity

(RH) approaches a user-defined setpoint. As a result,

the HL-69158NP provides more accurate control of duct

humidity and reduces condensation. As a stand-alone

controller, it can provide a proportional 0 VDC to 10 VDC

or 0 mA to 20 mA output based on its own setpoint, or

two-position Single-Pole, Single-Throw (SPST) Normally

Open (N.O.) output. The HL-69158NP also includes an

integral temperature sensor, which adds to the product's

versatility.

Features and benefits

Multi-functional device: provides several humidity

control applications: high limit or proportional override,

stand-alone proportional, or stand-alone two-position

All-plastic material for Duct Probe: improves

thermal performance and complies with Underwriters

Laboratories® Inc (UL) flammability ratings for plenum

use; complies with Blue Angel (Germany) and TCO'95

(Sweden) environmental regulations

Humidity and temperature sensors in one unit:

eliminates the need for separate sensors and reduces

installation time and cost

Adjustable RH setpoint and proportional band: enables

the user to define the maximum humidity level allowed in

the duct and reduces excessive humidification equipment

cycling

Product overview

Important: The HL-69158NP Multi-function Humidity

Device is intended to provide input to equipment

under normal operating conditions. Where failure

or malfunction of an HL-69158NP could lead to an

abnormal operating condition that could cause

personal injury or damage to the equipment or other

property, other devices (limit or safety controls) or

systems (alarm or supervisory) intended to warn

of, or protect against, failure or malfunction of

the HL-69158NP must be incorporated into and

maintained as part of the control system.

When it functions as an override device, the HL-69158NP

generates a 0 VDC to 10 VDC or 0 mA to 20 mA output

signal based on both setpoint and sensed humidity.

The HL-69158NP regulates duct humidity by overriding

a system controller’s demand for humidification when

humidity exceeds a user-defined setpoint. When used

as a stand-alone device, the HL-69158NP delivers a

proportional or On/Off relay output to a humidifier as

humidity approaches the preset setpoint. Power the

HL-69158NP from either a separate 24 VAC transformer or

directly from the controller.

The Johnson Controls sensor offers an all-plastic

enclosure, which reduces thermal biasing. This feature

lowers energy consumption, reduces condensation, and

eliminates the need for thermal compensation.

The temperature sensor's thin-film nickel material

provides 1,000 ohms of resistance at 70°F (21°C). The

temperature sensor operates independently of the

humidity control function. See Figure 2 for the resistance

versus temperature relationship for a nickel sensor.

Dimensions See the following figure for Humidity Device dimensions. Figure 4: HL-69158NP internal calculation and output selection Figure 3: HL-69158NP dimensions, in. (mm) Applications Proportional override device About this task: When you use the HL-69158NP device as a proportional override device with a system controller, the HL-69158NP operates as follows: 1. 2. The HL-69158NP accepts a 0 to 10 VDC or 0 to 20 mA input from a system controller. See Figure 4.
