Introduction

How to use this guide

The instructions is divided into six parts:

• Introduction

• Settings overview

• Daily use

• Maintenance

• Installation

• Check

Operation of the ECL Comfort is divided into two menu areas:

• Daily use (end user). Setting the desired ﬂow temperature, mode and schedule

• Maintenance (installer’s level). Setting of, for example, control functions.

Access to Maintenance (installer’s level) on the ECL Comfort 110: Press and hold “Arrow-down” button for 3 sec.

Basic principles of application 131 for ECL Comfort 110

Typically, the ﬂow temperature is always adjusted according to your requirements. The ﬂow temperature sensor S3 is the most important sensor. The desired ﬂow temperature at S3 is set in the ECL Comfort controller.

By means of the week schedule, the cooling circuit can be in ‘Comfort’ or ‘Saving’ mode (two values for the desired ﬂow temperature).

The motorized control valve M1 is opened gradually when the ﬂow temperature is higher than the desired ﬂow temperature and vice versa.

The return temperature S4 to the cooling supply (district cooling or cooling machine) should not be too low. If so, the desired ﬂow temperature can be adjusted (typically to a higher value), thus resulting in a gradual closing of the motorized control valve.

The circulation pump P1 is ON when the desired ﬂow temperature is lower than 40 °C (a selectable value).

The Standby mode maintains a selectable ﬂow temperature, for example 30 °C, provided the circulation pump is in operation.

If the measured room temperature does not equal the desired room temperature, the desired ﬂow temperature can be adjusted. The week schedule also controls two values (‘Comfort T’ and ‘Saving T’) for the desired room temperature. If the measured room temperature does not equal the desired room temperature, the desired ﬂow temperature can be adjusted.

The compensation temperature S1 can be arranged to inﬂuence the desired ﬂow temperature. The higher the compensation temperature, the lower the desired ﬂow temperature. An override input allows shift to constant Comfort or Saving mode.

°C (degrees Celsius) is an absolute temperature whereas K (Kelvin) is a relative temperature.

Setting range -20.0 . . . 50.0 °C

Setting the desired ﬂow temperature for Comfort mode. The same value is set in the End user menu as desired ﬂow temperature when in Comfort mode.

Saving T (desired ﬂow temperature in Saving mode) 2019

Setting range -20.0 . . . 50.0 °C

Temp. min. (minimum limitation of desired ﬂow temp.) 2177

Setting range -20 ... 50 °C

Set the minimum ﬂow temperature for your system. The desired ﬂow temperature will not be lower than this setting. Adjust the factory set ting, if required.

Temp. max. (maximum limitation of desired ﬂow temp.) 2178

Setting range -20 ... 50 °C

Set the maximum ﬂow temperature for your system. The desired ﬂow temperature will not be higher than this setting. Adjust the factory set ting, if required.

The setting for ‘Temp. min.’ has higher priority than ‘Temp. max.’.

Maintenance

Room T limit (room temperature limitation) 3000

This section is a general description for Room temperature limitation and is only relevant if you have installed a room temperature sensor (S2).

The ECL Comfort 110 adjusts the desired ﬂow temperature to compensate for the diﬀerence between the desired and the actual room temperature.

If the room temperature is higher than the desired value, the desired ﬂow temperature can be reduced. The ‘Gain-max.’ (Inﬂuence, max. room temp.) determines how much the desired ﬂow temperature should be reduced. Use this inﬂuence type to avoid a too high room temperature.

If the room temperature is lower than the desired value, the desired ﬂow temperature can be increased. The ‘Gain-min.´ (Inﬂuence, min. room temperature) determines how much the desired ﬂow temperature should be increased. Use this inﬂuence type to avoid a too low room temperature.

A typical setting will be -4.0 for ‘Gain-max.’ and 4.0 for ‘Gain-min.´

X = Room temperature

# 1 # = Desired room temperature

# 2 # = Negative inﬂuence (3182) when actual room temp. gets higher than desired

room temp.

# 3 # = Positive inﬂuence (3183) when actual room temp. gets lower than desired

room temp.

Maintenance

Comfort T (desired room temperature in Comfort mode) 3180

Setting range 5 . . . 40 °C

Setting the desired room temperature for Comfor t mode.

Saving T (desired room temperature in Saving mode) 3181

Setting range 5 . . . 40 °C

Setting the desired room temperature for Saving mode.

Gain - max. (room temp. limitation, maximum) 3182

Setting range -9.0 . . . 0.0

Determines how much the desired ﬂow temperature will be inﬂuenced (decreased) if the ac tual room

temperature gets higher than the desired room temperature (P control).

0.0: No inﬂuence

-2.0: Minor inﬂuence

-5.0: Medium inﬂuence

-9.9: Maximum inﬂuence

Gain - min. (room temp. limitation, minimum) 3183

Setting range 0.0 . . . 9.9

Determines how much the desired ﬂow temperature will be inﬂuenced (increased) if the actual room

temperature gets lower than the desired room temperature (P control).

9.9: Maximum inﬂuence

5.0: Medium inﬂuence

2.0: Minor inﬂuence

0.0: No inﬂuence

Intgr. time (Integration time) 3015

Setting range OFF / 1 . . . 50 s

Controls how fast the actual room temperature adapts to the desired room temperature (I control). The “Intgr. time” function can correct the desired ﬂow temperature with max. 8 degrees.

OFF: The control function is not inﬂuenced by the ‘Intgr. time’. Minor value: The desired room temperature is adapted quickly. Major value: The desired room temperature is adapted slowly.

Maintenance

Example 1

The actual room temperature is 2 degrees too low. The ‘Gain - max.’ is set to -3.5. The ‘Gain - min.’ is set to 2.0. Result: The desired ﬂow temperature is changed by 2 x 2.0 = 4.0 degrees.

Example 2

The actual room temperature is 2 degrees too high. The ‘Gain - max.’ is set to -3.5. The ‘Gain - min.’ is set to 2.0. Result: The desired ﬂow temperature is changed by 2 x (-3.5) = -7.0 degrees.
